Key Witness in Comey Case Attests to Justice Dept.’s Aggressive Tactics

Daniel C. Richman, a former aide to James Comey, accused the Justice Department of pursuing a “harassment campaign” as it sought testimony for investigations involving the former FBI director. His court filing describes aggressive and irregular tactics, adding detail to concerns about how the Trump administration’s cases against Comey have been handled.

Richman’s lawyers said prosecutors summoned two New York apartment building workers to a Florida grand jury after they refused an FBI agent entry to serve Richman with a subpoena, and threatened to charge him with obstruction. They said his lawyers had already agreed to accept the subpoena. Prosecutors gave conflicting accounts of whether Richman was a target or a subject and disagreed over immunity; he ultimately invoked his Fifth Amendment right. The filing supports CNN’s effort to unseal related court documents.
