Impeachment article has 200 cosponsors: US rep.

House Democrats are moving closer to launching a second impeachment effort against President Trump in the wake of insurrection at the Capitol -- an expedited push that could be voted out of the House as early as next week. 

House Judiciary Chairman Jerry Nadler, D-N.Y., signaled the speed at which the process could work in a statement late Thursday. 

"We have a limited period of time in which to act. The nation cannot afford a lengthy, drawn out process, and I support bringing articles of impeachment directly to the House floor," he said, suggesting that impeachment effort would bypass the House Judiciary Committee entirely.

Democrats are expected to introduce a privileged impeachment resolution in the House as soon as Monday, which could tee up debate and a floor vote by Wednesday, if House Majority Leader Steny Hoyer reconvenes the chamber. 

House Speaker Nancy Pelosi will convene Democrats for their first caucus call since events at the Capitol at noon Friday, where impeachment is expected to be a topic of discussion.

In the wake of Wednesday’s U.S. Capitol siege, at least 10 Trump administration officials have resigned.

Among them are five White House officials. These are Matthew Pottinger (deputy national security adviser), Tyler Goodspeed (acting chairman of the White House Council of Economic Advisers), Stephanie Grisham (Melania Trump’s chief of staff and spokeswoman), Rickie Niceta (White House social secretary) and Sarah Matthews (White House deputy press secretary).

Other officials who have resigned following Donald Trump's encouragement of Capitol protests, include Elaine Chao (secretary of transportation), John Costello, (deputy assistant secretary of commerce for intelligence and security) and Mick Mulvaney (U.S. special envoy to Northern Ireland and former White House chief of staff). 

Ryan Tully, the senior director for Europe and Russian affairs on the White House National Security Council has also willingly left his post, as has Betsy Devos, the secretary of education.

Education Secretary Betsy DeVos has resigned, according to a letter obtained by ABC News Thursday night.

She is the second Trump Cabinet member to step down in the wake of Wednesday's storming of the Capitol, following Transportation Secretary Elaine Chao's resignation earlier Thursday.

In her resignation letter, addressed to Trump, DeVos cited the president's role in Wednesday's "unconscionable" attack on the Capitol.  

"We should be highlighting and celebrating your Administration's many accomplishments on behalf of the American people," she wrote. "Instead, we are left to clean up the mess caused by violent protesters overrunning the U.S. Capitol in an attempt to undermine the people's business."

"There is no mistaking the impact your rhetoric had on the situation, and it is the inflection point for me," she added.

The resignation is effective Friday, according to the letter.

She joins a growing list of other Trump officials to resign following the Capitol breach.

Following the resignation of the House sergeant-at-arms and the Capitol police chief, Senate Majority Leader Mitch McConnell announced Thursday night that he’s received the resignation of the Senate sergeant-at-arms.

This comes following Senate Minority Leader Chuck Schumer’s statement earlier Thursday that he would fire the Senate sergeant-at-arms when Democrats claim the majority in the chamber if he did not resign.

“Today I requested and received the resignation of Michael Stenger, the Senate Sergeant at Arms and Doorkeeper, effective immediately," McConnell said in a statement Thursday.

“Deputy Sergeant at Arms Jennifer Hemingway will now serve the Senate as Acting Sergeant at Arms, pursuant to statute," McConnell continued. "I thank Jennifer in advance for her service as we begin to examine the serious failures that transpired yesterday and continue and strengthen our preparations for a safe and successful inauguration on January 20th.”
