There's a cancer on the presidency.

To me the fact that a Vice President can go to Capitol Hill and lobby for torture is just unbelievable. Just unbelievable! The fact that a small clique of attorneys in the Department of Justice can write how can we get around the Geneva Conventions so that we can torture during interrogations - I can't even get their mentally. And when you read their briefs, they didn't get there mentally.

Bush had expertise in one thing: How to run a Presidential campaign. He understands campaigns and Presidential politics. He has no interest or disposition or I think probably - he's not stupid, but he's not bright, he's not a rocket scientist - he isn't interested in policy.

I began by telling the President that there was a cancer growing on the presidency, and if the cancer was not removed, the president himself would be killed by it.

One of the reasons I thought a censure resolution was appropriate was because if somebody had censured Nixon or even if a resolution of either house had passed, saying what you're doing is unacceptable to Congress, that shot across the bow might have straightened him up.

Warrantless wiretapping is an impeachable offense. It couldn't be any clearer.

There are similiarities between Nixon and Trump, no question. But there are also big differences. Nixon was shy, private, he attacked the media behind closed doors and insulted people behind their backs, and we only know about it because of the taping system in the Oval Office. The dark side, the vengeance we only know because of these tapes. Trump is right out and front with it. He actually campaigned on how nasty he can be, which found resonance with enough voters to get him into the White House.
