I thought the reason Nixon resigned was because his fellow Republicans in the Senate came to him and said that the votes were there to impeach him.
As far as current law not allowing an open ended investigation, I saw Jonathon Turley on Fox News yesterday saying that Mueller’s mandate is worded so vaguely that he can investigate almost anything he wants.
But I did hear on Mark Levin yesterday that Levin’s reading of the Constitution allows unlimited pardon powers to the President, even pardoning himself. And that he doesn’t have to wait for any charges to be brought. He can exercise his pardon power whenever he wants to.
I remember Nixon well - the senators tried to convince him to stay on, assuring him they had the votes. But Nixon said no.
Rush had a long segment Friday on the text of the law, and said they clearly do not have authority to go into his business and tax returns. I believe Trump knows this and has already telegraphed his intention to take action - exactly what, only he knows.
That proposition is certainly arguable. I read the authorization as limited to the Trump campaign, which didn't even exist before 2015. It is also limited to criminal actions involving the campaign. IOW, if a campaign advisor is guilty of tax evasion, that has nothing to do with coordination between the Trump campaign and any Russian. Of course if people are lying about question in those confines, there is a legitimate case of false statements or obstruction.
The fact that other SC's got away with breaking the rules is not a license for Mueller to do so.
“Mueller’s mandate is worded so vaguely that he can investigate almost anything he wants.”
Ken Starr started by investigating Whitewater and we wound up with Lewinsky. Sucks having the shoe on the other foot, but its to be expected when you’re in power.
