Jeff Sessions says he is "confident" that Robert Mueller's probe of alleged Russian interference in the 2016 election will be handled "appropriately and with justification." In his only interview as he was leaving the Justice Department Wednesday, the former attorney general tells me if he had it to do over, he would still follow the advice of the department's career ethics officers and recuse himself from supervising the Mueller inquiry—the decision that infuriated President Trump. "No one is above supervision," he says. He hadn't expected the investigation to last so long, he said, and called the duration "unhealthy." But he says "the country is committed to this course."
