Matt Solomon joined the firm as a partner after serving for 15 years as a white-collar prosecutor and unit chief with the U.S. Department of Justice and as a senior enforcement official with the U.S. Securities and Exchange Commission—most recently as the SEC’s Chief Litigation Counsel.

At Cleary, Matt represents U.S. and foreign financial institutions, public companies, asset managers, and individual executives and employees, on a broad range of issues and disputes spanning from regulatory compliance and remediation advice to advocacy and litigation against the government and private parties. Matt leverages his background and experience in all three branches of government to represent his clients’ interests before regulatory, congressional and criminal authorities, including matters before the SEC, DOJ, CFTC and State Attorneys General.

Before joining Cleary, Matt served as the SEC’s Deputy Chief Litigation Counsel in 2012, and was elevated to be the agency’s top litigator in 2013. As Chief Litigation Counsel, Matt led the SEC’s 150-attorney national trial unit and supervised the SEC’s litigated cases in federal court and administrative proceedings. Matt also regularly advised the commissioners on complex issues arising in settled and litigated cases.

Prior to the SEC, Matt served in several prominent positions over 10 years with the DOJ and on Capitol Hill, including as an Assistant U.S. Attorney and then Chief of the Fraud Unit for the 350-lawyer U.S. Attorney’s Office for the District of Columbia, Counsel to the Chairman of the Senate Judiciary Committee working on criminal and national securities issues, and an Honors Program trial attorney in the Criminal Division’s Public Integrity Section.

Matt has tried more than 20 criminal and civil cases to verdict, including as lead counsel in complex, white-collar jury trials in the District for the District of Columbia, the Northern District of California, the Eastern District of Kentucky and the District of Puerto Rico. He has also briefed and argued cases in the U.S. Court of Appeals for the D.C. Circuit, the First Circuit and the Seventh Circuit.
