NEW YORK — Combative and insistent, President Donald Trump declared anew Tuesday “there is blame on both sides” for the deadly violence last weekend in Charlottesville, Va., appearing to once again equate the actions of white supremacist groups and those protesting them. He showed sympathy for the fringe groups’ efforts to preserve Confederate monuments.

The president’s comments effectively wiped away the more conventional statement he delivered at the White House a day earlier when he branded members of the KKK, neo-Nazis and white supremacists who take part in violence as “criminals and thugs.”

Trump’s advisers had hoped those remarks might quell a crush of criticism from Republicans, Democrats and business leaders. But the president’s retorts Tuesday renewed questions about why he seems to struggle to unequivocally condemn white nationalists.

The blowback was swift, including from fellow Republicans. Sen. Marco Rubio of Florida said Trump should not allow white supremacists “to share only part of the blame.” House Speaker Paul Ryan declared in a tweet that “white supremacy is repulsive” and there should be “no moral ambiguity,” though he did not specifically address the president.

Trump’s remarks were welcomed by former Ku Klux Klan leader David Duke, who tweeted: “Thank you President Trump for your honesty & courage to tell the truth.”

In the immediate aftermath, Trump placed the blame on “many sides.” On Monday, at the urging of his aides, he delivered a more direct condemnation of white supremacists. But he returned to his original arguments Tuesday during an impromptu news conference in the lobby of his Manhattan skyscraper, declaring “there are two sides to a story.”

He acknowledged there were “some very bad people” looking for trouble in the group protesting plans to remove the statue. “But you also had people that were very fine people, on both sides,” he said.

Trump sided with those seeking to maintain the monument to Lee, equating him with some of the nation’s founders who also owned slaves.

“So, this week it’s Robert E. Lee,” he said. “I noticed that Stonewall Jackson’s coming down.” I wonder, is it George Washington next week and is it Thomas Jefferson the week after? You really do have to ask yourself where does it stop?”

White House officials were caught off guard by his remarks Tuesday. He had signed off on a plan to not answer questions from journalists during an event touting infrastructure policies, according to a White House official not authorized to speak publicly.
