House Democrats on Monday announced that they plan to issue subpoenas for Robert Mueller’s “full and complete report, its underlying evidence and related matters” if Attorney General William Barr does not provide them by Tuesday’s deadline. Jerrold Nadler, the chair of the House Judiciary Committee, said Democrats will also subpoena Don McGahn, Steve Bannon, Hope Hicks, Reince Priebus, and Ann Donaldson, all of whom, Nadler says, may have received documents from the White House about the Russia probe. The subpoenas, which could go out as soon as this week, would represent the most concerted move yet by Democrats to get a full, un-redacted look at the special counsel’s report that Donald Trump claims, based on Barr’s four-page bottom-line summary, “exonerated” him on collusion and obstruction.

“As I have made clear, Congress requires the full and complete Special Counsel report, without redactions, as well as access to the underlying evidence,” Nadler said in a statement. “Attorney General Barr has thus far indicated he will not meet the April 2 deadline set by myself and five other Committee chairs, and refused to work with us to provide the full report, without redactions, to Congress.” Regarding the five individual subpoenas, Nadler noted that “not everyone” of the 81 people and entities to whom he sent document requests “has chosen to voluntarily cooperate with the Committee at this time,” and that he is “particularly concerned about reports that documents relevant to the Special Counsel investigation were sent outside the White House, waving applicable privileges. To this end, I have asked the Committee to authorize me to issue subpoenas, if necessary, to compel the production of documents and testimony.”

Mueller delivered his long-awaited 300-plus page report to the Department of Justice last month following an almost two-year probe that cast a dark shadow on Trump’s presidency, ensnaring some of his top associates and triggering near daily online tantrums. But the end of the Russia probe turned into a rare political win for the White House, with Barr writing that Mueller found no evidence of collusion between the Trump campaign and the Kremlin, and that while the special counsel left the obstruction question open, the attorney general and Rod Rosenstein didn’t believe there was evidence to establish the president committed an offense. Or, as Trump put it in a March 24 tweet: “No Collusion, No Obstruction, Complete and Total EXONERATION.”

Of course, that’s not necessarily the case. In his letter, Barr specifically quotes Mueller as saying the report “does not exonerate him” on the matter of obstruction. The attorney general says he’ll release a redacted version of the report by at least the middle of this month, and that he is open to testifying on its contents in early May. But Democrats are signaling they want more than that. In his announcement Monday, Nadler noted that his committee is seeking the report, evidence, and investigatory materials, citing information provided to lawmakers during Watergate, the Ken Starr investigation, and the D.O.J.’s own probe into Hillary Clinton as precedent.

“The public interest, and Congress’s constitutionally-grounded institutional interest, in the underlying evidence is much more profound and fundamental for Mueller’s investigation than any into Hillary Clinton’s e-mails, because it involves the President and his associates,” the statement Monday read. “The President has repeatedly sought to interfere in this investigation, and if the Department fails to make the Mueller report public in its entirety and turn over the underlying evidence to Congress, it may be actively facilitating a cover-up.”

It’s unclear whether Democrats will be able to get all the information they want, but the move sends a warning shot to the White House that they aren’t backing down from a fight—even as Trump and his associates attempt to go on the offensive.
