Around the time former President Donald Trump learned the FBI would examine a trove of sensitive documents he recently handed over to the National Archives, Trump turned to M. Evan Corcoran, a lawyer at the Baltimore firm Silverman, Thompson, Slutkin & White.

Corcoran was brought on as a member of Trump’s legal team on an April conference call without even meeting the former president, The Washington Post reported, citing an unnamed source. Since joining the team, Corcoran, a former federal prosecutor in Washington, D.C., has been the main point of contact for the U.S. Justice Department and National Archives over the handling of documents at Trump’s private club, Mar-a-Lago, an investigation that has quickly transformed into a dire legal threat for the former president.
