He added: "Whether there are mitigating circumstances remains to be seen". "He was using his power to do that, and when James Comey didn't go along with him, when he wasn't his boy, he fired him". He has committed an impeachable act and must be charged.
But while some Democrats, and Mr Trump's opponents in general, might be clamouring for an impeachment, it isn't as simple as Democrats deciding they don't like him.
There are multiple obstruction of justice statutes on the books. Those are Trump's worst numbers in that poll. In a press release on Green's website, he specifically called out the firing of former FBI Director James Comey, who was investigating possible ties between Russian Federation and Trump.
The White House denied the version of the conversation described by Comey's aides, telling The Post "the president has never asked Mr Comey or anyone else to end an investigation". I have said on previous occasions, and do now say again, the President should be impeached.
On their own, the words "I hope you can let this go" are likely not enough to trigger a criminal charge for obstructing justice.
"This is why we need a special prosecutor", he said. "Any one of these facts in isolation may be problematic, but may not be sufficient".
On CNN, Gergen said that "from a lay point of view" it appeared Trump was trying to impede the FBI's investigation.
"Our country is in a state of crisis", Green said. That's when, Comey later wrote, the president had asked him to ease off Flynn.
NPR asked a Comey associate this week why the Federal Bureau of Investigation director felt the need to take "very detailed" notes memorializing the conversation. "The people who are going to be responsible for carrying that out are probably the ones who are most hesitant to talk about it because they don't want to look like they jumped the gun in running to that process", Jentleson said.
The bookmaker Paddy Power Betfair PPB.I PPB.L said bettors there had laid out more than 5,000 pounds ($6,470) on an early departure for Trump in the hours after it was reported Trump had asked Comey to shut down the FBI's investigation of Russian Federation ties.
Defenders of Trump have been signaling they may attempt to turn the spotlight back onto Comey, asking why the former Federal Bureau of Investigation director didn't blow the whistle or quit after the February conversation with Trump.
The Houston Democrat also accused Trump of witness intimidation for warning Comey by tweet that their conversations may have been recorded.
Two Comey associates told NPR the former Federal Bureau of Investigation leader is confident in his assessments and willing to tell lawmakers and the public why he conducted himself the way he did.
Washington Democrats are warming up to the idea of impeaching President Trump, as opposition to the president drowns out all other causes in the party. And even if it did, they said, Comey would come out for the better.
