President Trump projected an air of calm on Wednesday after charges against his former campaign chief and a foreign policy aide roiled Washington, insisting to The New York Times that he was not “angry at anybody” and that investigations into his campaign’s links to Russia had not come near him personally.

“I’m not under investigation, as you know,” Mr. Trump said in a brief telephone call late Wednesday afternoon. Pointing to the indictment of his former campaign chief, Paul Manafort, the president said, “And even if you look at that, there’s not even a mention of Trump in there.”

“It has nothing to do with us,” Mr. Trump said.

He also pushed back against a report published Monday night by The Washington Post, which the president said described him as “angry at everybody.”

“I’m actually not angry at anybody,” Mr. Trump told The Times.

The phone call seemed intended to dispel the impression of a president and a White House under siege. The indictment of Mr. Manafort and his longtime deputy, Rick Gates, on Monday came as little surprise to Mr. Trump or his team, and they were relieved that the charges were not directly related to last year’s campaign. Instead, both were indicted on charges including money laundering, tax evasion and failing to properly disclose lobbying on behalf of foreign governments.
