I can't overstate the level of anxiety among sources close to Trump after the president told the NYT's Maggie Haberman last week he was willing and eager to submit himself to a live interview under oath with Special Counsel Robert Mueller.
What I'm hearing: One source, who knows Trump as well as anyone, told me he believes the president would be incapable of avoiding perjuring himself. "Trump doesn't deal in reality," the source said. "He creates his own reality and he actually believes it." (The president's attorney, Ty Cobb, did not respond to a request for comment.)
