Breaking: Roger Stone invokes Fifth Amendment right to reject Senate subpoena

Roger Stone, the longtime friend and former aide of President Donald Trump, invoked his Fifth Amendment privilege to reject providing documents and testimony under a subpoena from a U.S. Senate committee.

'Far too overreaching, far too wide ranging'

Sen. Dianne Feinstein (D-Calif.) revealed Stone's stonewalling in a tweet Tuesday that contained the letter from Stone's attorney, Grant Smith.

"Roger Stone's attorney sent a letter this week stating Stone won't provide documents or appear for an interview before the committee," Feinstein tweeted.

"On the advice of counsel, Mr. Stone will not produce the documents requested by you in your capacity as Ranking Minority Member of the Judiciary Committee," the letter read.

"The requests, as previously stated to staff," the letter continued, "are far too overbroad, far too overreaching, far too wide ranging both in their all-embracing list of persons to whom the request could relate with whom Mr. Stone has communicated over the past three years, and the 'documents concerning' imprecision of the requests."

Smith added that Stone had already provided testimony to the House Intelligence Committee.

Trump praised Stone on Monday for his comment that he would never testify against the president.

"'I will never testify against Trump.' This statement was recently made by Roger Stone," tweeted the president, "essentially stating that he will not be forced by a rogue and out of control prosecutor to make up lies and stories about 'President Trump.'"

He added, "Nice to know that some people still have 'guts!'"

Some pundits and critics of the president argued that the tweet constituted witness tampering, since the president has the power to pardon witnesses for federal crimes.

Stone responded to the president's tweet and the allegations of witness tampering via a Daily Caller reporter.

"Those who said the presidents warm and complementary tweet constitutes witness tampering should be reminded that I have never been contacted by any investigative body And therefore by definition this cannot be true," the statement read.
