Here is Carl Bernstein's entire statement to CNN:
"What there is a sense of, people I talk to in the White House and Republicans on Capitol Hill, is that the wheels are coming off this presidency. In the White House, there is an attempt by those closest to the President — especially [Chief of Staff John] Kelly, especially the military leaders — to try to constrain the president from his own inclinations to say wild things, to act irresponsibly. It’s almost as if there’s a protectorate around the President.
He’s constantly complaining, going into rages about the investigation, about disloyalty among his aides. It’s an extraordinary situation. Unlike anything I have seen in 50 years in Washington. They doubt his fitness to be president, they doubt his competence, they’re worried that he has to be restrained and constrained by these military leaders.
We’ve never seen this kind of chaos in a presidency before. This is different because it goes to the character and competence — a feeling that the president of the United States, including among those on the White House staff, may be unfit to hold the office. They are worried that we have a president of the United States who is really not stable in terms of the occupying the office and exercising the powers of the presidency. It is an extraordinary situation and that’s the real story.”
