While the White House has cooperated with Mueller’s investigation by providing documents and voluntary witness testimony, the President’s legal team argues that the President should not be treated like anyone else. Trump’s attorneys would like Mueller’s prosecutors to show that only the President can give them the information they require. The President’s team, one source said, is consulting with the White House counsel’s office and other outside legal experts given the implications of any decision about the President’s testimony on the office of the President.

The discussions about presidential testimony are ongoing and professional, says one source. But it is now clear where the President’s attorneys stand.

Mueller has made clear he is seeking a sit-down interview with the President, CNN reported last week. Mueller has even provided Trump’s attorneys with a range of topics he wants to ask about as part of ongoing negotiations regarding an interview with the President, sources familiar with the matter tell CNN.
