WASHINGTON — President Donald Trump’s racially fraught comments about a deadly neo-Nazi rally have thrust into the open some Republicans’ deeply held doubts about his competency and temperament, in an extraordinary public airing of worries and grievances about a sitting president by his own party.

Behind the high-profile denunciations voiced this week by GOP senators once considered Trump allies, scores of other, influential Republicans began to express grave concerns about the state of the Trump presidency. In interviews with Associated Press reporters across nine states, 25 Republican politicians, party officials, advisers and donors expressed worries about whether Trump has the self-discipline and capability to govern successfully.

Eric Cantor, the former House majority leader from Virginia, said Republicans signaled this week that Trump’s handling of the Charlottesville protests was “beyond just a distraction.”

“It was a turning point in terms of Republicans being able to say, we’re not even going to get close to that,” Cantor said.

Chip Lake, a Georgia-based GOP operative who did not vote for Trump in the general election, raised the prospect of the president leaving office before his term is up.

“It’s impossible to see a scenario under which this is sustainable under a four-year period,” Lake said.

Trump’s handling of the protests in Charlottesville, Va., has shaken his presidency unlike any of the other self-created crises that have rattled the White House during his seven months in office. Business leaders have bolted from White House councils, wary of being associated with the president. Military leaders distanced themselves from Trump’s assertion that “both sides” — the white supremacists and the counter-protesters — were to blame for the violence that left one protester dead. And some members of Trump’s own staff were outraged by his combative assertion that there were “very fine people” among those marching with the white supremacists, neo-Nazis and KKK members.

Importantly, the Republicans interviewed did not line up behind some course of action or an organized break with the president. Some expressed hope the recent shakeup of White House advisers might help Trump get back in control of his message and the GOP agenda.

Still, the blistering and blunt statements from some Republicans have marked a new phase. Until now, the party has largely kept its most troubling doubts about Trump to whispered, private conversations, fearful of alienating the president’s loyal supporters and upending long-sought GOP policy goals.

Tennessee Sen. Bob Corker, the chairman of the Foreign Relations Committee and a foreign policy ally of the Trump White House, delivered the sharpest criticism of Trump, declaring that the president “has not yet been able to demonstrate the stability nor some of the competence that he needs to” in dealing with crises.

Corker’s comments were echoed in the interviews with two dozen Republican officials after Trump expressed his views in Tuesday’s press conference. More than half spoke on the record, while the others insisted on anonymity in order to speak candidly about the man who leads their party and remains popular with the majority of GOP voters.

A handful defended Trump without reservation. South Carolina Gov. Henry McMaster, an early supporter of the president, said he “proudly” stands with Trump and said he was succeeding despite a “constant barrage of negative attacks from the left.”
