Democrats have been talking about it since before Donald Trump was sworn into office. On Wednesday, two congressmen officially filed an article of impeachment against the president.

Rep. Brad Sherman of California and Rep. Al Green of Texas issued a statement claiming the president obstructed justice by interfering with the federal investigation into Russian meddling into the 2016 presidential election.

The move is considered a longshot. It would need to pass the House with a majority, where right now Republicans enjoy a 24-seat advantage. The conviction also takes a two-thirds Senate vote and Republicans have a two-seat advantage.

Many House Democrats aren't on board with the move, hoping to instead focus on issues like the economy. 

Sherman cites that “high crimes and misdemeanors” took place when Trump allegedly pushed former FBI Director James Comey to drop the investigation of former national security advisor Michael Flynn, who is being investigated for his connections to Russia.

Sherman also cited that Trump's conversations and firing of Comey constituted obstruction of justice. Trump had said in an NBC television interview that Russia was on his mind when he fired Comey, a departure from the official statement.

The move comes one day after the president’s son, Donald Trump Jr., released emails on Twitter showing that he was open to receiving damaging information to the Hillary Clinton campaign even if it was part of a Kremlin-coordinated effort to help his father. The revelations came on the tail of a New York Times investigation about a June 2016 meeting between Trump Jr., presidential advisor and son-in-law Jared Kushner, then-campaign manager Paul Manafort and a Russian lawyer.

“Recent disclosures by Donald Trump Jr. indicate that Trump’s campaign was eager to receive assistance from Russia. It now seems likely that the President had something to hide when he tried to curtail the investigation of National Security Advisor Michael Flynn and the wider Russian probe.  I believe his conversations with, and subsequent firing of, FBI Director James Comey constitute Obstruction of Justice,” reads Sherman's statement. “Every day Democrats, Republicans, and the entire world are shocked by the latest example of America’s amateur President. Ignorance accompanied by a refusal to learn. Lack of impulse control, accompanied by a refusal to have his staff control his impulses. We’re no longer surprised by any action, no matter how far below the dignity of the office—and no matter how dangerous to the country.”

Sherman, who represents Los Angeles County's San Fernando Valley, is likely aware that the votes are not there for Trump to be impeached but may view this as an opportunity to push for changes within the White House.

“If Impeachment is real, if they actually see Articles, perhaps we will see incompetency replaced by care. Perhaps uncontrollable impulses will be controlled. And perhaps the danger our nation faces will be ameliorated,” continued the statement.

Sherman began circulating a draft of the article in June.
