Key congressional leaders are set to meet Thursday with federal law enforcement and intelligence bosses amid a slow-motion standoff over secret documents in the Russia investigation, the White House said on Tuesday.
Press secretary Sarah Sanders said that the White House had brokered a meeting at which two key Republican chairmen would hear from the leaders of the Justice Department, FBI and the intelligence community following weeks' worth of requests for the classified material.
No one from the White House is scheduled to be present, Sanders said — nor, at this point, are any senators or any Democrats, in defiance of a request from the Senate minority leader.
The members of Congress set to attend are Rep. Devin Nunes, R-Calif., the chairman of the House intelligence committee, and Rep. Trey Gowdy, chairman of the House Oversight Committee.
Those scheduled to attend from the executive branch are Director of National Intelligence Dan Coats, FBI Director Christopher Wray and Principal Associate Deputy Attorney General Ed O'Callaghan, Sanders said.
The meeting has been scheduled amid a gathering storm for the Justice Department and FBI following months of attacks by the president and his allies.
Trump has attacked one flank by demanding an expanded investigation into the ongoing inquiry about Russia's interference in the 2016 presidential election and whether anyone in his campaign was involved.
Trump and his supporters in Congress are expected to attack again in short order along a different line of advance, when Justice Department Inspector General Michael Horowitz releases his report about the FBI's 2016 investigation of Hillary Clinton.
That document is expected to appear soon, potentially next week.
The preliminary findings in the report already have cost one top FBI leader his job: former Deputy Director Andrew McCabe. The release of the full document is likely to invite new calls for potential criminal charges against McCabe and possibly former FBI Director James Comey.
It isn't clear how much the IG report could touch on the Russia investigation, which was still in its earlier stages at the time when much of the action on the Clinton case was taking place in 2016.
But Trump and Republicans want to hit DOJ and the FBI with both prongs of their assault at once to make the case that the agencies are infected with political bias and their work cannot be trusted.
"A lot of people are saying they had spies in my campaign," Trump told reporters on Tuesday. "If so, that would be a disgrace to this country. I hope there weren't, frankly ... but some man got paid based on what I read in the newspapers."
The White House and its supporters have been sandblasting the Justice Department and the FBI for months; the leaders of both law enforcement agencies have steadily been giving ground. Thursday's meeting is the latest example, although it wasn't clear precisely what documents Nunes and Gowdy are expecting and whether they will receive them then.
According to reports, the FBI paid a confidential informant to meet with Trump campaign workers who had or were suspected of having contacts with foreign governments in 2016. That followed a tip via Australia's Foreign Ministry that an American working for Trump in London had been meeting with Russian agents.
Trump cited the news stories to expand upon a theme he has sounded a few times before: that the Obama administration inappropriately spied on his campaign.
Previous charges about eavesdropping and "unmasking" were deflated, and skeptics say Trump is trying to change a story about potential wrongdoing by his campaign into one that casts doubt upon his predecessor, the Justice Department and the FBI.
Former Director of National Intelligence James Clapper told NPR on Tuesday there is a critical distinction between an investigation like the one the FBI reportedly conducted in 2016 and "spying" or "surveillance" and some other terms used lately.
"The point is: What is the objective? If the objective was, in fact, to surveil, observe the campaign to determine its political strategy or what it was trying to do to compete with the other campaign, that would not be good," Clapper said. "But the point here was to understand what the Russians were doing to try to infiltrate and gain leverage, access, influence, whatever they were trying to do. And there's a huge difference there."
The president's allies say they want to know for sure and have been demanding information about the Russia investigation from Deputy Attorney General Rod Rosenstein, who is overseeing the effort led by special counsel Robert Mueller.
"It's really important that we conduct the proper oversight of the executive branch to make sure that power is not or has not or will not be abused," House Speaker Paul Ryan, R-Wis., told reporters on Tuesday.
The House intelligence committee, Nunes, and other lawmakers threatened Rosenstein with contempt of Congress or, potentially, impeachment.
For a while, Rosenstein took a tough line, vowing that DOJ wouldn't be "extorted," but the battlefield shifted after the reports about the confidential informant.
Then Trump weighed in more strongly than ever with a "demand" for more information from the Justice Department, and Rosenstein acceded to it Monday. He traveled to the White House for a meeting with Trump, White House chief of staff John Kelly and FBI Director Christopher Wray.
One outcome was an acknowledgment by the Justice Department that its IG, Horowitz, will expand an inquiry he was already conducting into the ongoing Russia investigation to include its use of sources and surveillance.
For Trump's supporters in the House, that is not good enough. They want the Justice Department to appoint a second special counsel to look into the work of the first, Mueller. Attorney General Jeff Sessions has brought in additional investigators to look into the Russia case but so far has stopped short of agreeing that another special counsel is necessary.
The second outcome was the meeting on Thursday that Kelly has brokered between Hill leaders, the Justice Department and the FBI. Senate Minority Leader Chuck Schumer, D-N.Y., had urged the Trump administration to include Democrats but none were included in the White House's announcement.
"The only thing more outrageous than this meeting occurring at all is the fact that it's now partisan," Schumer said. "It is crystal clear that Chairman Nunes' intent is to interfere with the investigation, and Speaker Ryan is allowing it to happen."
"A dangerous precedent"
Democrats say the pressure Trump is bringing to bear on federal law enforcement is an inappropriate overreach of his authority against a Justice Department that is supposed to be able to act independently.
"The fact that ... Trump is DEMANDING the DOJ reveal confidential information about an ongoing criminal investigation is more evidence of potential abuses of power by the President," wrote New York Rep. Jerry Nadler, ranking member on the House Judiciary Committee, on Twitter. "This is not only a threat to the rule of law, but a dangerous precedent for our democracy."
Another Democrat, Connecticut Sen. Richard Blumenthal, said the legal and political complexities in Washington, D.C., missed the point: U.S. law enforcement and intelligence agencies must be able to protect their clandestine sources and operatives, he said.
"The review of highly classified documents in the midst of a highly charged partisan conflict raises the clear and present danger of illegal disclosure potentially catastrophic to confidential sources and operations," Blumenthal warned.
