Ask Sally Yates, under oath, if she knows how classified information got into the newspapers soon after she explained it to W.H. Counsel.— Donald J. Trump (@realDonaldTrump) May 8, 2017
There were concerns he had committed a felony by threatening a witness.
Or maybe it was the interview with Lester Holt, when he said "Russia is a made up story" and that's why he fired Comey.
So what is this?
James Comey better hope that there are no "tapes" of our conversations before he starts leaking to the press!— Donald J. Trump (@realDonaldTrump) May 12, 2017
Dick Durbin thinks its "dangerous":
“I think we ought to get to the bottom line here: President Trump is dangerous,” Durbin asserted on MSNBC’s Morning Joe, “dangerous because he may be obstructing justice, in terms of the investigation that really goes to the heart of our democracy —the accountability of the President, the people around him, to the rule of law — protecting our democracy from an invasion — a cyber-invasion by the Russians.”Dangerous because the President of the United States is threatening James Comey with exposure. If he were to demand money from Comey, we could call this blackmail. Set aside that, to Trump, any information in the press he doesn't like is a "leak"; that's stupid enough. But to tell Comey "If you don't toe the line, I will expose you!" is...dangerous. There really isn't another word for it. This is actually indefensible.
Once is happenstance, twice is coincidence....
