The U.S. House of Representatives is due to vote Tuesday on a measure authorizing lawsuits against Attorney General William Barr and former White House counsel Don McGahn over their refusal to cooperate with congressional subpoenas in connection with the investigation of Russian election interference.
Lawmakers want access to documents from special counsel Robert Mueller's report on his probe into whether President Donald Trump obstructed justice by trying to thwart the investigation, and for McGahn to testify about what took place inside the White House.
Authorizing the lawsuits would allow leaders in the Democratic-led House to go forward with those steps if they choose to do so at a later date.
McGahn was a key witness for Mueller, but has declined to testify before congressional committees, complying with the wishes of the White House. Mueller's team interviewed McGahn for 30 hours, with the lawyer telling prosecutors that Trump pressured him to try to get Mueller ousted from overseeing the investigation, a demand he ignored.
On Monday, the House reached a deal for the Justice Department to turn over crucial documents collected from the Mueller investigation.
Congressman Jerrold Nadler, chairman of the House Judiciary Committee, said the Justice Department would be opening Mueller's "most important files to us, providing us with key evidence that the special counsel used to assess whether" Trump and others "obstructed justice or were engaged in other misconduct."
Nadler said that all members of the Judiciary panel -- Democrats and Republicans alike -- would be able to see the documents, which he said "will allow us to perform our constitutional duties and decide how to respond to the allegations laid out against the president" by Mueller.
With the agreement, Nadler said he would withdraw a vote set for Tuesday whether to hold Barr in criminal contempt of Congress for failing to comply with the House committee's subpoena for the information.
Nadler said he is giving the Justice Department "time to demonstrate compliance with this agreement. If the department proceeds in good faith and we are able to obtain everything we need, then there will be no need to take further steps." But he said if the agreement collapses, it "will have no choice" but to pursue a court case to try to obtain the underlying documents from the Mueller probe that it is seeking.
Nadler's committee and others in the House are pursuing several investigations of Trump, along with the obstruction allegations, including about his business affairs, taxes and administration policies during his 29-month presidency. Trump has vowed to fight all Democratic subpoenas, but Nadler's agreement for information from the Mueller probe signals there also is room for negotiation rather than to let every dispute end in a legal fight in a courtroom.
On Monday, the Judiciary panel heard from former White House counsel John Dean, who was instrumental 46 years ago in the downfall of another U.S. president, Richard Nixon. At the time, Dean testified before Congress about White House corruption that led to Nixon's resignation as he was about to be impeached.
Mueller declined to exonerate Trump of obstruction allegations after a 22-month investigation. But he said that in any event Trump could not have been charged because a Justice Department policy prohibits filing criminal charges against sitting presidents. Subsequently, Barr and then-Deputy Attorney General Rod Rosenstein said criminal charges against Trump were not warranted.
About a quarter of the 235 Democrats in the 435-member House, along with one Republican, have called for Trump's impeachment or the start of an impeachment inquiry. But House Speaker Nancy Pelosi has resisted such calls, saying she prefers continued investigations by several House committees.
Last week, the political news site Politico reported that she told Democratic colleagues that she does not want Trump impeached, but "in prison," after facing criminal charges once he leaves office.
Trump retorted, "She's a nasty, vindictive, horrible person."
