White House deputy press secretary Sarah Sanders called the article of impeachment filed against President Trump by a Democratic congressman a "political game at its worst."

"I think that is utterly and completely ridiculous," Sanders said at the press briefing Wednesday, "and a political game at its worst."

Rep. Brad Sherman, D-Calif., introduced an article of impeachment earlier Wednesday accusing Trump of obstruction of justice.

"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 case of law and justice and to the manifest injury of people of the United States," Sherman's bill reads.

The California Democrat was joined by Rep. Al Green, D-Texas, in introducing the article of impeachment.

The two Democratic lawmakers argue the president obstructed justice when he asked former FBI Director James Comey to curtail the bureau's investigation into Mike Flynn, his former national security adviser, and subsequently fired Comey in May in what they said was an attempt to slow the investigation into ties between Trump campaign associates and Russia.

Sherman said in early June that Trump should be impeached, but he renewed his call for impeachment after emails from Donald Trump Jr. were published Tuesday.

The president's eldest son posted an email exchange to his Twitter account — before the New York Times published the contents of the exchange — in which Trump Jr. said he was interested in receiving damaging information about Hillary Clinton from a "Russian government lawyer."

The meeting was orchestrated by an intermediary, Rob Goldstone, who told Trump Jr. the information was part of the Russian government's efforts to help his father in the campaign.

"Recent disclosures by Donald Trump Jr. indicate that Trump's campaign was eager to receive assistance from Russia," Sherman said in a statement. "It now seems likely that the president had something to hide when he tried to curtail the investigation of National Security Adviser Michael Flynn and the wider Russia probe."
