Besieged from all quarters as it lurches from one crisis to another, the White House is already grappling with the possibility of a major staffing shake-up. Amid an endless stream of leaks and embarrassing gaffes that have tainted President Donald Trump’s first three weeks in office and sapped his administration’s momentum, blame is not in short supply in the West Wing. Last week, it was White House Press Secretary Sean Spicer who seemed to be on thin ice with his new boss. Now Chief of Staff Reince Priebus and National Security Adviser Mike Flynn are also facing heightened scrutiny as their names are dragged through the press, with a series of news reports suggesting that both men are quickly falling out of favor—and may soon be on the chopping block.

While Priebus has worked to regain control of the White House workflow in the wake of the administration’s botched rollout of Trump’s travel ban, the chief of staff continues to be blamed within Trumpworld for failing to assert his power more confidently. “I think there’s a lot of weakness coming out of the chief of staff,” Trump’s longtime friend and Mar-a-Lago member Chris Ruddy, the chief executive of Newsmax Media, said Sunday on CNN, after meeting with the president for drinks on Friday. “I think Reince Priebus [is a] good guy, well-intentioned, but he clearly doesn’t know how the federal agencies work. He doesn’t have a really good system. He doesn’t know how the communications flow,” he said, before adding that Trump wasn’t getting “the backup he needs from Priebus.” In a subsequent interview with The Washington Post, Ruddy reiterated his critiques of the former Republican National Committee chairman. After asserting “it’s pretty clear the guy is in way over his head,” Ruddy told the Post, “he botched this whole immigration rollout. This should’ve been a win for Donald, not two or three weeks of negative publicity.”

Later on Sunday, Ruddy walked back some of his remarks about Priebus after speaking with the embattled chief of staff. “Reince just briefed me on new WH plans. Impressive!” Ruddy tweeted. “Told him I have ‘open mind’ based on his results.” But in Trump’s, mind the damage was likely done. On Monday, Axios’s Mike Allen reported that Trump is already soliciting names to replace him in a “smooth” transition that could take up to a year and potentially end with Priebus moving into another Cabinet position. To add insult to injury, Priebus’s job could be taken by top Trump adviser Kellyanne Conway, who may be angling for the position. Politico reports that Trump aides have begun putting together a shortlist of potential candidates, including Conway, Rick Dearborn, and David Urban, as well as Trump economic adviser Gary Cohn, a Democrat and former Goldman Sachs president who has been flexing his muscles within the administration. Another possibility could be White House Senior Policy Adviser Stephen Miller, whose string of Sunday show interviews was widely seen as a tryout for a more prominent public role.

But if Priebus is being maneuvered toward an eventual, graceful demotion, Flynn may be headed for a more dramatic exit. The National Security adviser came under fire after a pair of deeply sourced reports in The Washington Post and The New York Times revealed that Flynn and Russian Ambassador Sergey Kislyak had discussed U.S. sanctions—leveled against Moscow in retaliation for the Kremlin’s alleged interference in the 2016 presidential election—before Trump’s inauguration, contrary to public statements by members of the Trump team, including Vice President Mike Pence. That bit of disloyalty has not gone over well within Trump’s inner circle: Trump himself has not come to Flynn’s defense, at first telling reporters that he hadn’t heard about the issue but would “look into that.” On Sunday, during interviews with ABC and NBC, Miller dodged questions about the retired general’s standing in the administration. “It’s not for me to tell you what’s in the president’s mind,” Miller told Chuck Todd on Meet the Press, adding that the White House “did not give me anything to say.” Flynn did fly to Trump’s gilded Palm Beach resort with the president this weekend to meet with Japanese Prime Minister Shinzo Abe, but reports are mixed on where he stands.

“It’s pretty clear the guy is in way over his head.”

A number of officials close to the president believe Flynn is on his way out. “Spread the butter: he is toast,” one source told Axios. “Lying to Pence damaged Pence's credibility and the administration's. That is an unpardonable sin.” To the Post, one source declared that the “knives are out for Flynn,” while another told the newspaper, “Flynn is running out of friends” and “the broad consensus in the White House is that he lied. . . . In a position that needs to be no drama, it’s nonstop drama. I would be very surprised if he lasts much longer.” Citing two sources with knowledge of the conversations, the Post reported that Trump expressed frustration with Flynn over the controversy.
