President Trump's personal lawyer Jay Sekulow said Sunday that — should the president decide not sit for an interview with special counsel Robert Mueller — his legal team would be prepared to fight any potential subpoena from Mueller's team in court.

The big picture: Sekulow told George Stephanopoulos on ABC's "This Week" that Trump has made it clear that he's willing to sit down with the special counsel, though his legal team still has some concerns. The team submitted a proposal to Mueller last month stating that the president would agree to an interview if questions are limited to potential Russian collusion, but Sekulow said the decision ultimately rests with Trump himself.
