“These were white supremacists and this was domestic terrorism,” he added, a description several of his colleagues used.
Mike Huckabee, the former Arkansas governor and the father of the White House press secretary, Sarah Huckabee Sanders, did not dispute Mr. Trump’s comments directly, but he called the behavior of white nationalists in Charlottesville “evil.”
Democrats have suggested that Mr. Trump is simply unwilling to alienate the segment of his white electoral base that embraces bigotry. The president has forcefully rejected any suggestion he harbors any racial or ethnic animosities, and points to his son-in-law, Jared Kushner, an observant Jew, and his daughter Ivanka, who converted to the faith, as proof of his inclusiveness.
In one Twitter post on Saturday, Mr. Trump nodded to that inclusiveness.
“We must remember this truth: No matter our color, creed, religion or political party, we are ALL AMERICANS FIRST,” the president wrote, a statement that had echoes of his campaign slogan, America First.
But like several other statements Mr. Trump made on Saturday, the tweet made no mention that the violence in Charlottesville was initiated by white supremacists brandishing anti-Semitic placards, Confederate battle flags, torches and a few Trump campaign signs.
Mr. Trump, the product of a well-to-do, predominantly white Queens enclave who in 1989 paid for a full-page ad in The New York Times calling for the death penalty for five black teenagers convicted but later exonerated of raping a white woman in Central Park, flirted with racial controversy during the 2016 campaign. He repeatedly expressed outrage that anyone could suggest he was prejudiced.
When he retweeted white supremacists’ accounts, he brushed aside questions about them. When he was asked about the support he had been given by David Duke, a former Ku Klux Klan leader, he chafed, insisting he didn’t know Mr. Duke.
Finally, at a news conference in South Carolina, Mr. Trump said “I disavow” when pressed on Mr. Duke. He later described Mr. Duke as a “bad person.”
When his social media director, Dan Scavino, posted an image on Mr. Trump’s Twitter feed with a Star of David near Hillary Clinton’s head, with money raining down, Mr. Trump rejected widespread criticism of the image as anti-Semitic. And after years of questioning President Barack Obama’s citizenship, he blamed others for raising the issue in the first place.
