"I don't think we're there yet", Arizona Sen.
Does this rise to the level of criminal obstruction of justice? This is mostly a symbolic event, but it does seem to be the first time a congressman has called for Trump to be impeached on the House floor. He added: "Whether there are mitigating circumstances remains to be seen".
Suggestions that Mr Trump may have sought to interfere in an FBI Investigation brings him into unsafe territory, however.
Jason Chaffetz, R-Utah, tweeted that he's asked Comey to testify at the hearing.
An emailed fundraising appeal by Trump's political organization and the Republican National Committee sent out after reports of the Comey memo said Trump was being victimized by an "unelected bureaucracy".
Putin told a news conference that he would be willing to turn over notes of Trump's meeting with the Russian diplomats if the White House agreed.
Walters' memos of Nixon's apparent obstruction of justice helped lead the way.
"I guess you could argue that stuff like [acquisition reform] is bipartisan, and it can press on regardless of that, but yeah, I am concerned that when it comes to budget, when it comes to some of the other things, that it makes it harder", Thornberry said.
"I hope you can see your way clear to letting this go, to letting Flynn go", Mr. Trump told Comey, according to the memo. Former President Bill Clinton was impeached on grounds of perjury and obstruction of justice while he was in the White House, but the Senate acquitted him in 1999, which is what happened to then-President Andrew Johnson in 1868. Law enforcement officials tell NBC that Manafort and Flynn "are formally considered "subjects" of a criminal investigation".
Nixon agreed. He told Haldeman and Ehrlichman to meet with Walters, a longtime Nixon loyalist whom the president had placed in the Central Intelligence Agency to monitor its director, Richard Helms, and give him the order to talk to Gray. The act has to be done corruptly.
Let's take a look at what other people are saying.
Trump, who has largely dismissed any impact Russian involvement may have had, fired Comey last week even as the FBI was investigating both Russian efforts to sway the election and possibly links to the Trump campaign. "Any one of these facts in isolation may be problematic but may not be sufficient". Oh, she's just trying to save her swing seat, you say?
Any investigation would pay close attention to the timeline.
Donald Trump's beleaguered White House was rocked Tuesday by a pair of explosive allegations - that he personally tried to quash an FBI investigation, and that he disclosed highly classified information to top Russian officials.
The White House vigorously denied it all.
But lawmakers are looking for more than Comey's written recollections of his dealings with the president.
With an FBI investigation gathering pace, its director, James Comey, was sacked last week. The associate was not authorized to discuss the memo by name and spoke on condition of anonymity.
Top members of the Senate Judiciary Committee have asked the Federal Bureau of Investigation to provide memos from Comey and for the White House to turn over any audio recordings that might exist of conversations with the now-fired director. Then, in a telling sign the temperature was going up, he said at a GOP dinner Tuesday night that the Trump situation has reached "Watergate size and scale".
"It's falling out of the trees, the evidence", he said.
In a weird twist on Wednesday, Russian President Vladimir Putin offered to turn over to Congress records of Trump's discussions.
This is the kind of conversation that rational, experienced presidents know not to have. The Washington Post reports that Comey's memo and Trump's disclosure of classified information to the Russians are "forcing a change in everyone's calculations".
The point is that the end could come even before Republican voters start heading for the hills.
"The American people don't participate on election day only".
