According to a source familiar with Mueller's letter to Barr and subsequent call with the attorney general, the letter from the special counsel's office came in on March 27. It was first reviewed by Deputy Attorney General Rod Rosenstein's office and is roughly a page in length. "Attorney General Barr also should not have withheld this letter from Congress for as long as he has," Nadler said. "The Attorney General has expressed some reluctance to appear before the House Judiciary Committee this Thursday," he added. He told CNN's Erin Burnett on "Erin Burnett OutFront" that Mueller's letter expressing concern to Barr "is both concerning and not surprising."
