Federal Crimes Defense Attorneys in Milwaukee, Wisconsin

When federal investigators show up at your door, everything about your legal situation changes. The agencies are better funded, the prosecutors carry deeper resources, and the penalties dwarf what state courts impose. A federal charge is not a state-level problem—it demands a legal team with real federal court experience.

At Gimbel, Reilly, Guerin & Brown, our federal criminal defense attorneys have defended Wisconsin clients in the U.S. District Court for the Eastern District of Wisconsin, the 7th Circuit Court of Appeals, and the U.S. Supreme Court. The firm’s federal practice includes attorneys who previously served as federal prosecutors, including service as an Assistant U.S. Attorney, giving direct insight into how the government builds and prosecutes its cases. GRGB holds a U.S. News & World Report First Tier ranking in White Collar Criminal Defense.

What Makes Federal Charges Different from State Charges?

Federal crimes are prosecuted in U.S. District Court under federal statutes, investigated by federal agencies like the FBI, DEA, and IRS, and sentenced under a framework that combines the advisory Federal Sentencing Guidelines with statutory mandatory minimums for certain offenses. Federal parole was abolished for offenses committed on or after November 1, 1987. The differences between a federal charge and a state charge affect every stage of the case, from investigation through sentencing, and the consequences are almost always more severe.

Federal jurisdiction typically applies when a crime involves interstate commerce, federal property, federal agencies, or violations of specific federal statutes. The FBI, DEA, IRS Criminal Investigation, ATF, and other agencies often conduct investigations that last months or years before a single charge is filed. Federal law enforcement data published by the Bureau of Justice Statistics consistently shows that a substantial majority of federal suspects in concluded matters are prosecuted, with the highest rates in drug and weapons cases.

Once charges are filed, the case moves through a system that operates very differently from Wisconsin circuit court:

• Grand jury indictment: Federal felony charges are ordinarily initiated by indictment from a grand jury of 16 to 23 citizens. Under Fed. R. Crim. P. 7(b), a defendant may waive indictment for a non-capital offense and proceed by information, which is common in negotiated resolutions.
• Restrictive release conditions: Detention decisions are made under the Bail Reform Act, 18 U.S.C. § 3142, based on an individualized assessment of flight risk, danger to the community, and whether conditions of release can address both. Certain offenses carry rebuttable presumptions in favor of detention, and detention is ordered more often than in Wisconsin state court.
• Guidelines sentencing: Ranges are calculated using a table based on offense level and criminal history category. The Guidelines have been advisory rather than binding since United States v. Booker in 2005, though the calculated range still anchors the sentencing decision.
• No parole: Parole was abolished in the federal system for modern offenses. Under 18 U.S.C. § 3624(b), a person serving more than a year may earn up to 54 days of good conduct time per year, which works out to serving roughly 85 percent of the imposed term at maximum credit. First Step Act earned time credits may apply in addition for eligible individuals, generally toward placement in prerelease custody rather than as a reduction of the term itself, and eligibility depends on the offense, risk assessment, and program participation.

Federal Agencies That Investigate Cases in Wisconsin

Multiple federal agencies maintain offices in the Milwaukee area and conduct investigations across Wisconsin:

• FBI Milwaukee Division
• DEA Milwaukee District Office
• IRS Criminal Investigation
• ATF Milwaukee Field Division
• HHS Office of Inspector General
• U.S. Postal Inspection Service
• U.S. Secret Service
• Homeland Security Investigations

Federal investigations can run for months or years before charges are filed, which makes early attorney involvement critical—before you say anything to an agent that could be used against you.

The Federal Court System in Wisconsin

Wisconsin has two federal judicial districts. The Eastern District of Wisconsin, headquartered at the federal courthouse at 517 E. Wisconsin Avenue in Milwaukee, handles the bulk of federal criminal cases in the state. Its jurisdiction covers the southeastern counties including Milwaukee, Waukesha, Racine, Kenosha, Ozaukee, Washington, Sheboygan, and Fond du Lac, with a secondary division in Green Bay.

The Western District of Wisconsin operates from the Robert W. Kastenmeier U.S. Courthouse at 120 N. Henry Street in Madison and covers Dane County and western Wisconsin. Appeals from both districts go to the U.S. Court of Appeals for the 7th Circuit in Chicago, with further review available by petition for certiorari to the U.S. Supreme Court. GRGB practices in both Wisconsin federal districts and before the 7th Circuit.

Federal Crimes We Defend

GRGB’s federal criminal defense practice covers a wide range of federal offenses—from healthcare fraud and drug trafficking to white collar financial crimes, RICO charges, and computer-related offenses. Each category carries distinct sentencing exposure and requires specific defense strategies.

Healthcare Fraud (18 U.S.C. § 1347)

Federal healthcare fraud charges target schemes to defraud health care benefit programs, including Medicare, Medicaid, and private insurers. Common allegations include billing for services not rendered, upcoding, kickback arrangements, and phantom patient schemes. Under 18 U.S.C. § 1347, penalties reach up to 10 years per count, up to 20 years if the violation results in serious bodily injury, and up to life if it results in death. Convictions also commonly carry restitution, forfeiture, and exclusion from federal health care programs.

The Department of Justice has made healthcare fraud a national enforcement priority, and its annual national takedown actions have charged hundreds of defendants in alleged schemes totaling billions of dollars. GRGB works with forensic accountants and medical billing professionals to challenge the government’s fraud theories at every stage.

Federal Drug Charges (21 U.S.C. § 841)

Federal drug trafficking and distribution charges carry some of the harshest penalties in the federal system. Under 21 U.S.C. § 841, mandatory minimum sentences of 5 or 10 years attach at specified drug types and quantities, and prior qualifying convictions can increase those minimums substantially. These cases typically involve the DEA, multi-agency task forces, and extensive wiretap evidence. Relief from a mandatory minimum is possible in defined circumstances, including statutory safety valve eligibility and government motions based on substantial assistance, which is one reason early and experienced counsel matters.

Federal drug cases in Wisconsin are distinct from state possession charges in both scale and consequence. A state marijuana possession charge might result in a fine. A federal trafficking charge involving the same substance can mean years in federal prison without the possibility of parole.

White Collar Crimes

White collar federal charges encompass wire fraud (18 U.S.C. § 1343), mail fraud (§ 1341), money laundering (§ 1956), tax evasion, campaign finance violations, securities fraud, embezzlement, and public corruption including bid rigging. These charges frequently run in combination—a single scheme can generate wire fraud, money laundering, and tax counts simultaneously, with each count adding to the sentencing exposure.

RICO Charges

The Racketeer Influenced and Corrupt Organizations Act targets patterns of racketeering activity conducted through an enterprise. RICO cases are complex, multi-defendant proceedings, and 18 U.S.C. § 1963 provides for up to 20 years of imprisonment, or life where the underlying racketeering activity carries a life maximum, along with asset forfeiture. The government must establish an enterprise, a pattern of qualifying predicate acts, and the continuity that ties them together. Each of those elements is a point at which the prosecution’s theory can be contested, and conspiracy liability under § 1962(d) raises separate questions from the substantive offense.

Computer-Related Federal Offenses

Computer fraud under the Computer Fraud and Abuse Act, cybercrime charges, and identity theft have become increasingly common federal prosecutions. These cases involve significant digital forensic evidence, and mounting an effective defense requires counsel who can retain independent technical analysts to examine the government’s digital evidence and investigative methods.

Why GRGB? Former Federal Prosecutors on Your Side

How Does the Federal Criminal Process Work in Wisconsin?

The federal criminal process follows a structured path from investigation through trial, sentencing, and appeal. Understanding each phase helps defendants and their families make informed decisions at every stage. The general framework below applies to most cases, though the path in any individual case depends on the charges and the evidence.

Step 1 — Federal Investigation

Federal investigations often begin months or years before charges are filed. Agencies like the FBI, DEA, and IRS conduct surveillance, issue grand jury subpoenas, interview witnesses, and execute search warrants. The moment you suspect you are under federal investigation—whether through a target letter, a visit from agents, or a subpoena to a colleague—contacting a federal defense attorney is the single most important step you can take. Communications with your attorney for the purpose of obtaining legal advice are generally protected by attorney-client privilege, subject to recognized exceptions.

Step 2 — Grand Jury and Indictment

Federal felony charges ordinarily begin with prosecutors presenting evidence to a grand jury of 16 to 23 citizens. The grand jury votes in secret, and the defense has no right to appear or cross-examine witnesses. If 12 or more jurors find probable cause, the grand jury returns an indictment. A defendant may also waive indictment and proceed by information. In some cases, counsel engaged before the grand jury votes can present information to prosecutors that affects the charging decision.

Step 3 — Arraignment and Detention Hearing

Shortly after indictment, the defendant appears before a federal magistrate judge at the Milwaukee federal courthouse. Release decisions in federal court are made under the Bail Reform Act and are more restrictive in practice than in Wisconsin state court, with rebuttable presumptions favoring detention for certain offenses. The determination is individualized, and advocacy at the detention hearing can be the difference between awaiting trial in custody and remaining at home.

Step 4 — Discovery, Pretrial Motions, and Plea Negotiations

Federal discovery can involve massive document productions, digital evidence, wiretap recordings, and forensic reports. Pretrial motions to suppress evidence or dismiss counts can reshape the case before it ever reaches a jury. The large majority of federal cases resolve through plea agreements, and the terms of those agreements are shaped by the strength of the record the defense develops beforehand. GRGB prepares every case as though it will be tried.

Step 5 — Trial and Sentencing

Federal criminal trials are tried to a jury of 12, and a verdict must be unanimous. The parties may stipulate to a smaller jury, and the court may permit a verdict from 11 jurors if one is excused for good cause after deliberations begin. Sentencing follows the advisory Federal Sentencing Guidelines, a point system that calculates a range based on offense level and criminal history category, alongside any statutory mandatory minimum that applies. Advocacy at sentencing, including departure and variance arguments backed by mitigation evidence, can make a substantial difference in the sentence imposed.

Step 6 — Federal Appeals and Post-Conviction Relief

A guilty verdict or unfavorable sentence is not always the final word. GRGB handles appeals in the 7th Circuit Court of Appeals and petitions for certiorari to the U.S. Supreme Court. The firm also pursues post-conviction motions for sentence reduction under 18 U.S.C. § 3582(c) and, in appropriate cases, claims of actual innocence. GRGB currently represents clients serving life and multiple life sentences who are seeking appellate relief.

What Should I Do If I Receive a Federal Target Letter or Learn I Am Under Investigation?

A target letter from the U.S. Attorney’s office means the government has identified you as a likely defendant in a federal criminal case. This is the most critical moment to retain counsel—before charges are filed, the window to influence the outcome is at its widest.

Do not speak to federal agents without an attorney present. Invoke your right to counsel immediately. Even casual conversations with investigators can produce statements that are used against you at trial. A false statement to a federal agent can itself be charged under 18 U.S.C. § 1001.

An experienced federal defense attorney engaged at the pre-indictment stage can review what the government appears to have, present favorable information to prosecutors, negotiate pre-indictment resolutions, and in some cases affect whether charges are filed at all. Outcomes at this stage depend on the facts and on the government’s own assessment of its case, but the opportunity to be heard is far greater before an indictment is returned than after.

Federal Cases Across Wisconsin and Beyond

GRGB handles federal criminal cases in both Wisconsin federal districts and beyond. In the Eastern District of Wisconsin, the firm practices at the Milwaukee federal courthouse at 517 E. Wisconsin Avenue—less than a mile from GRGB’s offices at 330 East Kilbourn Avenue. The firm’s federal practice extends to the Western District in Madison, the 7th Circuit Court of Appeals in Chicago, and the U.S. Supreme Court.

Clients come from across the Milwaukee metro area—Waukesha, Brookfield, Wauwatosa, Shorewood, Racine, and Kenosha—as well as Ozaukee and Washington Counties. The firm’s federal practice also reaches beyond Wisconsin, and GRGB currently handles matters with national and international dimensions.

Wherever your federal case arises—from Milwaukee’s Eastern District courthouse to Madison’s Kastenmeier Courthouse to the 7th Circuit in Chicago—GRGB practices in those courts. Contact the firm at 414-271-1440 to schedule your consultation.

Frequently Asked Questions About Federal Criminal Defense

What is the difference between a federal crime and a state crime in Wisconsin?

Federal crimes violate U.S. statutes, are investigated by federal agencies like the FBI and DEA, and are prosecuted in U.S. District Court by Assistant U.S. Attorneys. State crimes are prosecuted in Wisconsin circuit courts under state law. The most significant practical differences are that federal sentencing runs through the advisory Guidelines alongside statutory mandatory minimums for certain offenses, and that there is no parole in the federal system for modern offenses.

How do federal sentencing guidelines work?

The Federal Sentencing Guidelines use a two-axis table. One axis measures the offense level—based on the crime type, amount of loss, the defendant’s role, and other factors. The other measures criminal history. The intersection produces a range that the court must calculate and consider, but which has been advisory rather than binding since United States v. Booker. A court may sentence outside the range after weighing the statutory sentencing factors, though a statutory mandatory minimum sets a floor the Guidelines cannot lower. GRGB’s attorneys work to contest the offense level calculation and argue for downward variances and departures.

Can I go to federal prison for a first offense?

Yes. Federal prison sentences are regularly imposed on first-time offenders, particularly in drug trafficking and fraud cases, and Sentencing Commission data shows imprisonment in the large majority of federal cases. A defense attorney can argue for a below-guideline sentence through variance motions, safety valve eligibility where it applies, cooperation agreements, and mitigation evidence.

What is a federal grand jury, and do I have to testify?

A federal grand jury is a panel of 16 to 23 citizens that reviews evidence in secret to decide whether to return an indictment. You have a Fifth Amendment right not to incriminate yourself. If you are subpoenaed to appear before a grand jury, retain counsel immediately—there is a critical distinction between being treated as a witness, a subject, or a target, and an attorney can work to determine your status and protect your rights.

How long does a federal criminal case take?

Federal investigations can run for years before charges are filed. Once a case is in U.S. District Court, disposition commonly takes the better part of a year, and complex white-collar and RICO cases often take significantly longer. GRGB remains actively engaged throughout the entire timeline—from the first sign of investigation through trial and any appeal.

Does GRGB handle federal appeals?

Yes. GRGB handles criminal appeals in the U.S. Court of Appeals for the 7th Circuit and petitions for certiorari to the U.S. Supreme Court. The firm also pursues post-conviction motions for sentence reduction and claims of actual innocence, and currently represents clients serving life sentences who are seeking post-conviction relief through the federal appellate courts.

Why does it matter that GRGB has former federal prosecutors on staff?

Former federal prosecutors understand how investigations are built—the evidence agents seek, the witnesses they cultivate, and how charging decisions get made. GRGB’s defense team includes attorneys who worked inside the U.S. Attorney’s Office, and that experience informs strategy at every stage of a federal case.
