In an interview with MSNBC news Historian Michael Beschloss, said:
“It goes way beyond Nixon. Nixon never would have said something like that as president, nor would any other modern president. And that’s why I think what he said was ominous, bordering on shocking. Because you have this president making this claim that he can do whatever he wants with the Justice Department. No other modern president would agree with that. He goes on to say he has the right to open or end an investigation. Well, guess what investigation he’s eluding to? And the other thing he says is that for purposes of – this is almost his quote – for purposes of hopefully that I’m going to be treated well, I’ve stayed uninvolved, referring to the Mueller investigation. What he’s telling us, let’s listen to this very carefully, is there is a serious chance that if he feels he’s not being treated fairly, he will not be uninvolved and he may try to shut down this investigation. This is a real warning.”
