Jon is co–chair of the firm’s White Collar & Government Investigations Practice Group and is nationally regarded as a go-to attorney in complex white collar criminal defense matters. Jon is one of two attorneys in Florida who was designated by Chambers USA as an “eminent practitioner” in the white-collar field. He represents individuals and corporations in white-collar criminal defense matters. This frequently includes matters that receive national media attention, such as his representation of a former public official in the House of Representatives’ impeachment inquiry into President Donald J. Trump. Jon also served on Florida Attorney General Pam Bondi's transition team.
Jon has long been recognized as one of the most talented white collar criminal defense attorneys in the country. Chambers USA consistently ranks Jon at the highest levels, including Band-1 in the state of Florida. Through Chambers USA, peers and colleagues have reported that Jon is “an outstanding negotiator whose legal knowledge is second to none,” and “one of the most sought-after attorneys in the United States.” Chambers USA further notes that Jon, “understands both sides and he commands respect from the judges,” and, “has extraordinary credibility with prosecutors and gets excellent results for his clients.” Jon is celebrated for being “a big-picture guy who knows how to focus on the micro and the macro,” and “a rock star and amazing to watch in action.”
He is experienced in representing corporations and individuals in grand jury investigations, internal investigations, and diverse and complex criminal litigation, including large scale document reviews and productions. He has represented clients in almost every substantive area of concentration, including healthcare fraud, securities fraud, financial institution fraud, Foreign Corrupt Practices Act (FCPA) violations, money laundering, criminal anti–trust violations, tax fraud, mortgage fraud, and various fraudulent investment schemes. He also is experienced in representing defendants at sentencing hearings.
Jon is the attorney representative for the Eleventh Circuit on the Practitioner’s Advisory Group (PAG) to the United States Sentencing Commission. He is also the Co-Chair of the Prosecution / Defense Liaison Committee in the Southern District of Florida, which meets with supervisors in the U.S. Attorney's Office for the Southern District of Florida to discuss policies and procedures in the District.
Jon has vast prior experience working for the government as a prosecutor. He was an Assistant U.S. Attorney in the Southern District of New York and in the District of Connecticut. Most notably, he also served as an Assistant Special Watergate Prosecutor under Special Prosecutors Archibald Cox and Leon Jaworski. His responsibilities extended to supervising grand jury matters and functioning as trial counsel in resulting litigation. He participated in legal efforts to obtain and review secret White House tapes to determine whether criminal conduct had taken place in the Oval Office and among senior Presidential staff members. He also participated in litigating an issue of first impression in the Fifth Circuit, which tested the power of the judiciary when ruling on a government Motion to Dismiss a criminal proceeding. Jon also served as a Special Assistant to the Attorney General of the United States supervising a grand jury investigation to determine if an ambassadorship was awarded as a quid pro quo for a political contribution.
Jon also was the First Assistant U.S. Attorney in the Southern District of Florida, where he supervised all major criminal and civil cases within that judicial district. In U.S. v. Fedorenko, he was the chief prosecutor in a civil denaturalization proceeding against a World War II guard at the Nazi death camp at Treblinka, Poland. Witnesses, who had escaped from Treblinka during the war, traveled to the United States to identify Fedorenko and testify about his war crimes during the trial. The case was ultimately heard by the Supreme Court of the United States, which upheld the decision of the Fifth Circuit and ordered that Fedorenko be denaturalized.
Jon has also served on numerous court committees. He has been a member of the Southern District of Florida Federal Judicial Nominating Commission, which interviewed candidates for the federal bench and made recommendations to the Senators; the Chair of the U.S. Magistrate Merit Selection Panel, which recommends to the District Court finalists for Magistrate Judge positions; the Trial Experience Committee of the Attorney Admissions Program; and the Advisory Committee on Rules and Procedures for the U.S. District Court.
Jon was a member of Governor Ron DeSantis’ Transition Advisory Committee on Public Safety.
Jon is a perennial panelist at the ABA White Collar Institute, the preeminent white collar criminal defense group in the country.

In 2024, Jon appeared with a federal district court judge for a presentation at a global law firm, ranked in the AmLaw top 10, called, “Then and Now: A Conversation on Antisemitism.”
Jon often appears as a legal analyst on national cable television and radio shows, including Fox News, Fox Nation, MSNBC, CNN, and NPR. He was an opinion contributor for The Hill, for which he published several articles. He is frequently quoted for his legal analysis on current events for publications including Law360, the Miami Herald, CNN online, NewsMax, and Bloomberg News, among others.
