Sessions recused himself from the Russia investigation in March, despite criticisms from Trump. It was reported earlier this month that Trump ordered White House counsel Don McGahn to block Sessions from recusing himself, but the attorney general do so anyway.

Comey was also interviewed last year by Mueller's team.

Trump has repeatedly dismissed the Russia probe as a witch hunt and denied collusion.

Mueller reportedly wants to question Trump on his decision to fire Comey and the departure of his former national security adviser, Michael Flynn.

Two people familiar with Mueller’s investigation told The Washington Post that Trump’s legal team could present conditions for Trump to interview with Mueller’s investigators as soon as next week.
