President Trump and Vice President Pence met in the Oval Office Monday evening, according to a senior Trump administration official.

It was the first time they had met since last week.

According to the official, "the two had a good conversation, discussing the week ahead and reflecting on the last four years of the administration's work and accomplishments."

"They reiterated that those who broke the law and stormed the Capitol last week do not represent the America first movement backed by 75 million Americans and pledged to continue the work on behalf of the country for the remainder of their term," the official said.

House Republican Leader Kevin McCarthy said in a letter to Republican colleagues that he does not support the Democrats' effort to impeach Trump.

"Personally, I continue to believe that an impeachment at this time would have the opposite effect of bringing our country together when we need to get America back on a path towards unity and civility," McCarthy wrote in his letter that he sent Monday, obtained by ABC News.

Instead, he is pushing for four other alternatives to impeachment, including a resolution of censure under the rules of the House, a bipartisan commission to investigate the circumstances surrounding the attack, reforming the Electoral Count Act of 1887 and legislation to promote voter confidence in future federal elections

Acting Homeland Security Secretary Chad Wolf is resigning from the Trump administration effective at 11:59 p.m. Monday, according to an internal message sent to staff at the department, citing "recent events."

"I am saddened to take this step, as it was my intention to serve the Department until the end of this Administration. Unfortunately, this action is warranted by recent events, including the ongoing and meritless court rulings regarding the validity of my authority as Acting Secretary. These events and concerns increasingly serve to divert attention and resources away from the important work of the Department in this critical time of a transition of power," he said in an email to colleagues.

The House of Representatives is expected to return at 9 a.m. Tuesday to debate and pass a bill via a roll call vote demanding Vice President Mike Pence mobilize the Cabinet to remove Trump from office through the 25th Amendment. The vote is expected around 7:30 p.m., according to House Majority Leader Steny Hoyer’s office.

Democrats will give Pence "24 hours after passage" to respond, said House Speaker Nancy Pelosi in a statement earlier Monday, otherwise they will likely move forward with an impeachment vote on Wednesday, setting up Trump to be the first president in U.S. history impeached twice.

“The President’s threat to America is urgent, and so too will be our action,” Pelosi said in the statement.

As of right now, no Republicans have signed on to the legislation that calls on Pence to invoke the 25th Amendment, which is a likely indicator as to what happens with a potential vote on impeachment.

But sources tell ABC News that it’s possible some Republicans may vote to impeach Trump.

The single article of impeachment charging Trump with “incitement of insurrection” also cites Trump's call with the Georgia Republican secretary of state where he urged him to "find" enough votes for Trump to win the state and, separately, cites the Constitution's 14th Amendment, noting that it "prohibits any person who has 'engaged in insurrection or rebellion against' the United States" from holding office.

With just nine full days left in office, Trump is facing a possible historic second impeachment as House Speaker Nancy Pelosi, in the wake of the Capitol Hill assault, warns if he doesn't resign, or if his Cabinet doesn't move to remove him.

Democrats are taking steps Monday morning in the House to remove Trump, beginning at a pro forma session on the House Floor at 11 a.m.

Majority House Leader Steny Hoyer, D-Md., will request unanimous consent to bring up the "Raskin resolution" which calls on Vice President Mike Pence to ask the president's Cabinet to activate the 25th Amendment -- effectively declaring Trump incapable of executing the duties of his office and making Pence the acting president.

If Hoyer fails to get unanimous consent, with Republicans expected to object, Democrats will hold a private caucus call at 2 p.m. and bring up the legislation again Tuesday to a full floor vote. Then, Pelosi said, in a letter to her colleagues Sunday night, "We are calling on the Vice President to respond within 24 hours," and if he does not, they "will proceed with bringing impeachment legislation to the Floor."

With both resignation and removal by the 25th Amendment unlikely, impeachment legislation -- on one article charging "incitement of insurrection," according to a draft -- will likely hit the House floor Wednesday. Rep. David Cicilline, D-R.I., said on Twitter Sunday night that the article has at least 210 cosponsors.

But Democrats are divided over Democratic Majority Whip Jim Clyburn suggesting over the weekend that the House wait until after Biden's first 100 days to submit the article to the Senate to trigger a trial. And there's almost no chance Senate Majority Leader Mitch McConnell will call the Senate back sooner than Jan. 19.

Democrats like Rep. Alexandria Ocasio Cortez argue despite an inconvenient timeline the process allows Congress an outlet to hold Trump accountable. Pelosi told CBS' "60 Minutes" Sunday, Trump had "done something so serious that there should be prosecution against him."
