president through a mock interview to see if he is capable of testifying to special counsel robert mueller without perjuring himself. woodward reports that trump fails the test. and what's even more remarkable is that dowd and trump's current attorney, jay sekulow, then go and re-enact the scene to robert mueller himself in an attempt to convince mueller that trump is incapable of getting through an interview. according to woodward, mueller isn't convinced and responds, quote, i need the president's testimony. and then mueller says, i want to know what was his intent on comey. i want to see if there was corrupt intent. dave, christine? >> all right, jamie, thank you. some of the most startling quotes in woodward's book come from two of his top aides. chief of staff john kelly reported in the book to have called the president an idiot and unhinged.
