President Donald Trump said he has “full confidence” in White House lawyer Ty Cobb, who has urged Trump to cooperate with Special Counsel Robert Mueller’s Russia probe. In a tweet on Thursday, Mr. Trump said “I have agreed with the historically cooperative, disciplined approach that we have engaged in with Robert Mueller (Unlike the Clintons!) He continued, “I have full confidence in Ty Cobb, my Special Counsel, and have been fully advised throughout each phase of this process.” Some of Trump’s strongest supporters have been urging the president to take a more aggressive position toward Mueller’s investigation, in particular after FBI agents descended on the office and home of Trump lawyer Michael Cohen. Trump has called the FBI raid an “attack on our country.” However in a separate Twitter post Thursday, Mr. Trump denied reports that he had tried to dismiss Mueller last year. “If I wanted to fire Robert Mueller in December, as reported by the Failing New York Times, I would have fired him,” Trump said. Meanwhile, a bipartisan group of U.S. senators introduced legislation to protect the special counsel from being fired without cause.
