The special counsel’s team could interview Trump soon on some limited portion of questions — possibly within the next several weeks, according to a person close to the president, who spoke on the condition of anonymity to describe internal conversations.

“This is moving faster than anyone really realizes,” the person said. Trump is comfortable participating in an interview and believes it would put to rest questions about whether his campaign coordinated with Russia in the 2016 election, the person added.
