Absolutely. Three US presidents have faced impeachment or have been impeached in the history of the US.
Some, such as the online political stock market PredictIt, have seen record volume on contracts focused on whether Mr Trump will be impeached.
Impeachment is exceedingly rare.
"We've been betting on impeachment for all recent USA presidents but, even at the height of the Lewinsky scandal, Bill Clinton was only ever 6-1 to be impeached", Price said. As the president, he has the constitutional power to decide whether or not the United States government considers information classified and he can discuss USA intelligence with whomever he wants.
The White House issued a furious denial after the notes were disclosed late Tuesday, near the end of a tumultuous day spent beating back potentially disastrous news reports from dawn to dusk. The Clinton and Nixon examples offer crucial lessons about the importance of slowing down and ensuring that the public is confident that the gravity of the alleged conduct warrants the extraordinary and fundamentally undemocratic remedy of Congress removing the president from office.
Although the founders wanted a way to remove "obnoxious" federal officials, as Ben Franklin put it, they did not make the process easy. That article is then brought and debated before the full House.
A simple majority is required for this to occur.
Second, the president would face trial in the Senate.
Two-thirds of the Senate must vote in favor of conviction if he or she is to be removed from office. That led to a wave of anger toward him in Congress that resulted in his impeachment on grounds that included being "unmindful of the high duties of his oath of office".
Then there's the political equation.
After winning the presidential election, Donald Trump said he would maintain ownership of his global business empire but hand off control to his two oldest sons while he serves as the president. In the cases of Nixon and Clinton, the opposition party controlled Congress.
Part of the trouble for the Trump White House isn't just the "size and scale" of Watergate, but the eerie similarities.
Ryan essentially echoed this message in a closed-door meeting of House Republicans earlier Wednesday morning.
Pressure has built on Trump since he fired FBI chief James Comey last week amid an investigation into Russia's alleged meddling in the USA electoral process. He also details Trump's possible leak of classified information to a Russian foreign minister last week.
"Reluctantly, Wolf, I have to say yes, simply because obstruction of justice is such a serious offense". John McCain, a Republican from Arizona.
Asked about Trump's performance, Ryan said, "Obviously he clearly did have a bad two weeks". He said during a news conference that "we are prepared to go there and explain our point of view to Congress if necessary". Even though Johnson came within a single vote of being convicted in the Senate, most historians have dismissed his impeachment as driven more by partisanship than a proper basis for impeachment and removal.
They urged him to sign a discharge petition introduced on the House of Representatives floor Wednesday to force action on House Resolution 356, a Democratic-backed bill to create a special, independent investigative commission to oversee the matter.
Foes accused Johnson of violating a controversial and short-lived 1867 law, known as the Tenure of Office Act, meant to prevent him from firing cabinet members without Senate approval.
