The U.S. House Judiciary Committee has voted to authorize a subpoena to obtain Special Counsel Robert Mueller III’s full report and its underlying evidence.

Panel chairman Jerrold Nadler, D-New York, said in opening remarks Wednesday that he asked U.S. Attorney General William Barr to work with the committee to get access to material covered under grand jury secrecy rules. “He has so far refused,” Nadler said. He said he would give Barr time to change his mind, but would issue subpoenas for the materials if they could not reach a deal.
