Impeachment is the process by which the president can be removed from power if it is believed he or she has "engaged in treason, bribery, or other high crimes and misdemeanours". "The presidency now has kinglike qualities, and we have a child upon the throne", Douthat said. Other Democrats have repeatedly echoed their thoughts.
No Democrat was in more demand Wednesday than Texas Rep. Al Green - the seven-term Democrat from Houston who held a hometown news conference two days before calling for the impeachment of President Donald Trump. The articles of impeachment against Trump might look remarkably similar to those levied against Nixon and Clinton.
Justin Amash, a Republican who has been critical of Trump in the past, agreed that if the Comey memo proves to be true, it would constitute grounds for impeachment. As Reason's Scott Shackford has noted, that's what Joe Biden would call a "big fucking deal" if it turns out to exist and to be accurate. The President must be impeached.
According to a poll from the Public Poling Policy organization, public support for impeaching Trump is now at 48 percent, surpassing Nixon's impeachment numbers 16 months after the Watergate break-in.
Let's be clear: Trump hasn't been accused of any crimes.
Green says he plans to introduce a resolution to impeach President Trump "soon", though he wouldn't give a definitive date.
He said that democracy was at risk over the sacking of FBI Director James Comey because he was investigating the president.
In the end, it comes down to members of Congress deciding that Trump did something that meets constitutional requirements for impeachment.
Currently, there are 238 Republican House members.
Though considered the first step towards removal from office, it doesn't necessarily mean the president will be kicked out.
The House of Representatives and Senate Intelligence committees have ongoing investigations into alleged Russian interference with the 2016 USA presidential election. A simple majority of votes within the House is enough to officially impeach the president.
Also, Comey was despised among Republicans and Democrats. Chief Justice John G. Roberts Jr. would preside over the trial.
Two-thirds of the Senate, or 67 senators, are required to convict.
This move, coming hot on the heels of reports on Tuesday evening that Comey kept memos detailing his conversations with Trump.
And history is on Trump's side. It's one of the few ways a president can leave office early.
Andrew Johnson became the first president to be impeached in 1868.
Republicans, who egged on impeachment talk in the Bush years, are cautiously sounding the same notes now. Congress has initiated a mere 62 impeachment proceedings in US history, with 19 cases going to trial and just eight federal officials being convicted.
A base united in opposition to Trump has been feeding into the impeachment narrative since the moment he entered the White House in January. He hadn't introduced an official impeachment resolution yet and was planning more town halls on the subject.
Richard Nixon resigned in 1974 to avoid certain impeachment by Congress over the Watergate scandal. He later was pardoned by his successor, President Gerald Ford. Most claimed Johnson violated the Constitution when he removed the secretary of war from office.
