House Democrats Subpoena Full Mueller Report, and the Underlying Evidence

Given the sensitive nature of the information, Mr. Boyd wrote, “all individuals reviewing the less-redacted version” must agree to keep the newly unredacted information confidential.

Mr. Nadler rejected the proposed accommodation as insufficient on Friday.

He has repeatedly asked the Justice Department to join him in requesting that a court unseal the grand jury information, in particular, for Congress to review privately. Mr. Barr, in turn, has so far rejected that request, and Republicans have backed him up, arguing in effect that the Judiciary Committee is not entitled to such information unless the House authorizes a formal impeachment inquiry.

“I am open to working with the department to reach a reasonable accommodation for access to these materials,” Mr. Nadler said in his statement. “However, I cannot accept any proposal which leaves most of Congress in the dark, as they grapple with their duties of legislation, oversight and constitutional accountability.”

Mr. Nadler’s requests put him at odds with his Senate counterpart, Lindsey Graham, Republican of South Carolina and the leader of the Judiciary Committee. Mr. Graham has spoken supportively of Mr. Barr, said he accepts his conclusions and pledged to scrutinize the investigators who targeted Mr. Trump and his campaign.

Like most other Senate Republicans, though, Mr. Graham has not commented on the details of Mr. Mueller’s report, which painted a damning portrait of Mr. Trump’s norm-bending campaign to thwart the special counsel investigation.

Senator Rob Portman, Republican of Ohio, was one of only a few Republican lawmakers who addressed those details, if only briefly. In a statement, he said that the “report documents a number of actions taken by the president or his associates that were inappropriate,” though he added without additional comment that Mr. Barr and Rod J. Rosenstein, the deputy attorney general, had concluded the evidence did not warrant charging Mr. Trump.
