Rep. Brad Sherman, D-Calif., on Wednesday introduced an article of impeachment accusing President Trump of obstruction of justice and alleging that he interfered with the ongoing federal investigation into Russia's meddling in the 2016 election.

Sherman revealed the article Wednesday afternoon and argued that Trump fired former FBI Director James Comey in an effort to slow the federal investigation into Russian interference, which amounts to obstruction of justice. He said that Trump "has prevented, obstructed and impeded the administration of justice during a federal investigation" by asking Comey to stop looking into potential violations by former National Security Adviser Mike Flynn and threatening Comey before eventually terminating him.

"Donald John Trump has acted in a manner contrary to his trust as President and subversive of constitutional government, to the great prejudice of the cause of law and justice and to the manifest injury of people of the United States," Sherman said in his impeachment bill.

The California Democrat first called for Trump's impeachment in early June, but admitted that there will be no movement on any such article given that Republicans control Congress.

The only other lawmaker who signed onto the bill is Rep. Al Green, D-Texas, who has also called for Trump's impeachment. Led by House Minority Leader Nancy Pelosi, D-Calif., most Democrats have tempered calls for impeachment and want to see facts before any actions of this kind are taken.

After Sherman made his initial call to impeach Trump, multiple House Democrats questioned his decision in a caucus meeting. Rep. Mike Capuano, D-Mass., said an early decision on impeachment could have a negative impact on rank-and-file members.

The push by Sherman comes a day after Donald Trump Jr. released an email chain showing that he was warned about Russian support for the Trump campaign, just before he met with a Russian lawyer with ties to the Kremlin who was offering damaging information to Hillary Clinton's campaign.

Trump Jr. said that he will cooperate with all relevant Senate committees about the meeting, which he initially said was supposed to be about Russian adoptions.
