Sixty-two Democrats have signed on to a letter to Speaker Nancy Pelosi calling on House leaders to immediately reconvene the House of Representatives to reckon with the "assault on our democracy" that took place at the Capitol this week.

"We could take up the question of whether President Trump should be censured or impeached for encouraging a violent attack on the United States Congress, as well as Representative Raskin’s proposal that Congress appoint a body, as provided by the 25th Amendment, to determine whether the President is fit to discharge the powers and duties of his office," the letter reads.

It comes ahead of House Democrats convening by phone at noon to discuss a path forward on getting Trump out of office.

Republican Sen. Ben Sasse of Nebraska said Friday morning he would consider moving on articles of impeachment if the House brought charges against the president to the Senate.

"The House, if they come together and have a process, I will consider whatever articles they might move because as I've told you, I believe the president has disregarded his oath of office," Sasse told "CBS This Morning."

"He swore an oath to the American people to preserve, protect and defend the constitution. He acted against that. What he did was wicked," Sasse said.

Sasse is the first GOP senator to publicly express an openness to impeachment since Wednesday's insurrection at the Capitol. In the president's impeachment trial last year, Sen. Mitt Romney of Utah was the only Republican to vote to remove Trump from office.

Attorney General for the District of Columbia Karl Racine faulted Capitol Hill Police for failing to contain Wednesday’s insurrection but said his office will also investigate those who incited the mob -- including the president.

"Clearly, the Capitol was ground central in the mob’s behavior. Donald Trump Jr., Rudy Giuliani, even the president were calling on supporters and hate groups to go to the Capitol, and in Rudy’s words, 'exercise combat justice,'" Racine told "Good Morning America" Anchor Cecilia Vega in an interview Friday morning. "We’re going to investigate not only the mob, but those who incited the violence."

Racine also said authorities would use the Internet to identify the rioters who violated the Capitol and noted, "More people died at the Capitol of the United States than in Benghazi."

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 an interview on Fox News Monday morning, Republican senatorial candidate David Perdue said that while he and his wife have "repeatedly" tested negative for coronavirus, he is still quarantining after coming into "close contact" last week with a campaign staffer who tested positive and hopes to participate in

"I’m going to participate hopefully tonight by virtually in this rally, but I’m so excited that President Trump is coming again," Perdue said, going on to paint the dire picture of the country if Democrats win.

Asked what he wants to hear the president say Monday, Perdue said: "First of all this is the last opportunity we will have to protect everything that we’ve accomplished in the last four years. The second thing is the last line of defense to stop the Democrats from perpetrating this radical socialist agenda. It’s as simple as that." 

As he did Sunday, Perdue blasted disclosure of the call between Trump and Secretary of State Brad Raffensperger and defended the president.

"To have a state-wide elected official, regardless of party, tape unknowing -- to tape without disclosing a conversation -- private conversation of the president of the United States and then leaking it to the press is disgusting," Perdue said.

When asked if he was concerned that GOP voters may be discouraged from participating in the aftermath of a general election Republicans continue to contest, Perdue said, "Well that’s what the Democrats want." Trump himself acknowledged post-election chaos may hinder turnout in the runoffs during his call with Raffensperger Saturday -- and blamed the secretary for it.
