Matthew C. Solomon has significant experience in complex and high-stakes civil and criminal matters, having served for 15 years with the U.S. Department of Justice and the U.S. Securities and Exchange Commission—including most recently as the SEC’s Chief Litigation Counsel.

Matt’s practice focuses on securities enforcement, complex commercial litigation and white-collar criminal defense. He joined the firm as a partner in 2017.

Matt joined the SEC’s Enforcement Division as 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 litigation efforts in federal courts and administrative proceedings, as conducted by 150 trial attorneys in Washington, D.C., and the SEC’s 11 regional offices. He also worked closely with SEC investigative staff nationwide in the supervision and negotiation of cases filed as settled matters, and regularly advised the Director of Enforcement and the Commission on litigation strategy and risk.

Under Matt’s leadership, the SEC prevailed in a number of high-profile federal trials, and he personally represented the agency in some of its most sensitive cases. Matt also spearheaded the SEC’s litigation response to significant legal and policy issues, such as developments in insider trading law and challenges to the SEC’s administrative courts.

Before joining the SEC, Matt served in several prominent positions with the DOJ, including as an Assistant U.S. Attorney and then Chief of the Fraud Unit for the U.S. Attorney’s Office for the District of Columbia, as a DOJ detailee-counsel to the Senate Judiciary Committee, and as an Honors Program trial lawyer in the Criminal Division’s Public Integrity Section.

Matt’s prosecutions at DOJ included convictions in a number of high-profile cases, including NASA’s former Chief of Staff in a week-long corruption jury trial in the District for the District of Columbia; two highly placed political party operatives in a six-week tax and corruption jury trial in the District of Puerto Rico; an IRS Special Agent in a two-week corruption jury trial in the Northern District of California; and a federal congressional candidate and sitting state legislator who both pleaded guilty to federal campaign finance abuses.
