A Democratic representative has introduced the first formal article of impeachment against President Donald Trump.
Representative Brad Sherman alleges Mr Trump committed obstruction of justice by firing former FBI Director James Comey amid agency investigations into Russian meddling in the US election.
"Such conduct," Mr Sherman writes in the article, "warrants impeachment and trial, and removal from office."
The Constitution allows impeachment in the case of “treason, bribery, or other high crimes and misdemeanours". Obstruction of justice is a felony offence.
To take effect, however, articles of impeachment must pass the House by a majority vote – an unlikely outcome in today's Republican-controlled chamber. So far, only one other Democrat – Texas Representative Al Green – has publicly expressed support for impeachment proceedings.
When Mr Sherman started circulating a draft article last month, fellow Democratic Representative Michael Capuano reportedly stood up at a party meeting and denounced him as selfish.
In a statement issued Wednesday, Mr Sherman said he does not expect impeachment to happen immediately. Instead, he hopes the article will inspire an "intervention" in the White House, and encourage the executive branch to control its "uncontrollable impulses".
If not, he said, Republicans will eventually begin to support the impeachment effort.
Mr Sherman's article cites several of Mr Trump's reported actions – both before and after Mr Comey's termination – as evidence of obstructing justice.
First, Mr Sherman cites Mr Comey's allegation that the President asked him to drop an investigation into former national security adviser Michael Flynn. In a Senate hearing last month, Mr Comey said Mr Trump had privately asked him to "let this go".
Mr Sherman also faults Mr Trump for firing the former FBI Director, and claims he did so in response to Mr Comey's handling of the Russia investigation.
While the White House provided several different accounts of Mr Comey's firing, the President eventually told NBC's Lester Holt: "When I decided to just do it, I said to myself -- I said, you know, this Russia thing with Trump and Russia is a made-up story."
Finally, the Representative cites Mr Trump's reported comments after the firing, in which he allegedly told Russian officials: “I faced great pressure because of Russia. That’s taken off.”
After Mr Comey's firing, the Department of Justice appointed a special prosecutor to oversee their investigation into Russian meddling. The special prosecutor, Robert Mueller, is reportedly investigating Mr Trump for possible obstruction of justice, but has yet to release any findings.
