Trump ally Roger Stone has invoked the Fifth Amendment in his justification for refusing to cooperate with a congressional request for documents.

In a letter sent to the office of Rep. Jerry Nadler (D-NY), Stone attorney Grant Smith argued that cooperation with the House Judiciary Committee's request could incriminate his client.

"Since the time of Mr. Stone's testimony before the House Intelligence Committee, and principally related to the events of that day, Mr. Stone has become a defendant in a case brought by the government," wrote Smith. "As a current criminal defendant, with the presumption of innocence guaranteed to him, it is not in Mr. Stone's best interests to participate in any additional proceedings."

Smith added that Stone's decision to invoke the Fifth "must be understood by all to be an assertion of the Constitutional right by an individual citizen, who is currently defending his innocence."
