Everybody We Know Robert Mueller Has Interviewed in the Trump Investigation So Far

Special counsel Robert Mueller and congressional investigators have interviewed roughly 50 people who work at the White House or were involved in Donald Trump's campaign.

Based on a compilation of CBS of known interviews, that number includes at least 20 White House employees and one Cabinet official: Attorney General Jeff Sessions.

So far, it has not included Trump himself, though the president has said he'd "love" to talk to Mueller.

There may be more.
