The president objected to his decision to recuse himself from the Russia investigation. Mr. Trump, who had told aides that he needed a loyalist overseeing the inquiry, berated Mr. Sessions and told him he should reverse his decision, an unusual and potentially inappropriate request.
Mr. Sessions refused.
The confrontation, which has not been previously reported, is being investigated by the special counsel, Robert S. Mueller III, as are the president’s public and private attacks on Mr. Sessions and efforts to get him to resign. Mr. Trump dwelled on the recusal for months, according to confidants and current and former administration officials who described his behavior toward the attorney general.
