“He’s really getting into boy-who-cried-wolf territory with this round of stories, saying he’s considering resigning, especially because the president is just not going to change his behavior,” said Matt Miller, a former aide to Obama-era Attorney General Eric Holder. “If you don’t resign, you look both feckless and insincere.”

Barr’s allies on Wednesday sought to play down the Trump-Barr tension, predicting that it would soon pass — or at least hoping that it would.

“I think this will blow over,” said Mike Davis, who previously served as the Senate Judiciary Committee's nominations counsel under Sen. Chuck Grassley (R-Iowa). “It would be a huge loss if Barr left. I think he’s been a fantastic attorney general."

People close to Barr and Trump said Barr’s concerns were genuine but did not signal an imminent blowup.

“There is some tension. The tension has been public. Bill hasn’t hidden what his concern is,” said one person familiar with their interactions. “They’ve both been public about it. I think they still a have a very good relationship.”

The source also dismissed the notion that the attorney general is on the verge of quitting.

“I can imagine a circumstance where he said, ‘I’m not dealing with this. I may resign.’ That may be a general conversation that was misinterpreted,” said the Barr ally. “Barr is not hiding the fact it’s difficult for him. But it doesn’t mean he’s leaving.”

One former senior administration official said the media reports about Barr’s resignation threat looks more like it was done “to try to create a rift” between his attorney general and the president.

“I just can’t think a guy in my mind as savvy as Barr, that he’d actually tell people that,” said the former official. “I have a hard time believing that’s what happening. That’s tempting fate. Now you’re going to get the president pissed off and he’s going to say, ‘You know what? Fire him.’”

Still, one sign that Barr is genuinely distressed is the joint statement of support GOP congressional leaders suddenly issued for the attorney general Tuesday. Senate Majority Leader Mitch McConnell, House Minority Leader Kevin McCarthy and Senate Judiciary Chairman Lindsey Graham all saluted Barr as “a man of the highest character and unquestionable integrity.”

The statement came as a petition by former Justice Department officials calling on Barr to resign surpassed 2,000 signatures.

At Barr’s only public event Wednesday, he got a vote of confidence from FBI Director Christopher Wray, even through the two men offered notably different takes on the recent inspector general report on surveillance abuses — with Barr striking a more Trump-friendly stance.

“He is no stranger to tackling challenges,” Wray said of Barr, calling him “my friend” and noting his long history at DOJ, including his prior stint as attorney general three decades ago. “We need that type of strong leadership.”

Barr continued to build common cause with the U.S. national security establishment by joining in an op-ed released Wednesday warning about the threat of foreign interference in the 2020 election. The topic is known to be one whose mere mention irritates the president, but the piece soft-pedaled the part most galling to Trump, making just one passing reference to Russia.

For now, the guessing game inside and outside the Justice Department is just how much interference and commentary from the president Barr will stomach before moving on.

Barr has built up a thick skin during his two stints as attorney, so no one expects him to resign because Trump tweeted some unkind videos from Fox Business News. But worrisome for Barr is that one of Trump’s retweets Wednesday highlighted past presidents’ efforts to influence Justice Department investigations.

Barr’s effectiveness is now directly tied to the intensity of Trump’s focus on his DOJ-related grievances. If there are many days when the president obsesses about them publicly, the attorney general’s tenure may be limited.

On the other hand, Trump is eminently distractable and sometimes seems more interested in whacking the Democratic presidential candidates than going after the deep state.

As Trump’s political schedule ramps up in the coming months, the chief risk for Barr may be that the president decides to make railing against prosecutors, judges and even jurors a staple of his campaign stump speech, delving into the topic again and again.

But to really put the attorney general in an excruciating fix, those attacks would have to coincide with Barr’s efforts to exert control over the department — a perfect storm that occurred last week, but that might not be whipped up to the same degree again before the election.

“People at the Justice Department will tolerate the attorney general getting involved in their cases for legitimate reasons,” said Miller, the former Holder aide. “The AG has the right to do that. They’ll even tolerate it if there’s some deniability of a political motive, but when the president removes any plausible deniability, there’s nothing for the career employees to do but revolt to keep their own integrity intact.”
