- The interviews are major developments in Mueller's investigation
- The White House said it is cooperating
Sessions was questioned for several hours last week as part of the investigation into Russia's meddling in the 2016 election. Investigators spoke with Comey last year, sources told CNN.
The interviews, part of the investigation into Russia's meddling in the election and whether President Donald Trump obstructed justice since taking office, are major developments in Mueller's investigation.
Sessions was questioned last Wednesday, a source close to Sessions told CNN, and a source familiar with the discussion said it was the first time the attorney general was interviewed. He was not under subpoena, the source familiar added.
The New York Times, citing two people briefed on the matter, reported
Tuesday that Comey was asked about memos he wrote about interactions with the President.
Neither meeting was revealed until Tuesday.
Justice Department spokeswoman Sarah Isgur Flores confirmed the Sessions meeting, which was also first reported
by The New York Times. She declined to say if the attorney general turned over any documents or communications to Mueller's office.
