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.

The number of National Guard troops deployed around next week's inauguration could rise from at least 10,000 to 15,000, the National Guard’s top general said Monday.

"Support requests from the Secret Service, Capitol Police and Park Police have been authorized to provide up to 15,000 Guard members to meet current and future support requirements," Gen. Daniel Hokanson, the chief of the National Guard Bureau, told reporters on a phone briefing. "They are troops that have been requested to support security, logistics liaison and communication missions."

Hokanson said that there are currently 6,200 Guardsmen in the District, and there would be 10,000 in place by Saturday.

The National Guard has always participated in inaugurations, and there were 9,000 members on hand last year, but because of the coronavirus pandemic, the number had been reduced to 5,000 for 2021. Last week's insurrection at the Capitol changed those plans, and Pentagon spokesperson Jonathan Hoffman additionally made clear that the Guardsmen will be remaining in Washington after Inauguration Day.

"We're not looking at Jan. 20 as the last day and people will pack up and go home at the conclusion of all the events," he said. "There will be some elements that will remain for a brief period to ensure safety and security in the days following the inauguration as well."

Hokanson, the chief of the National Guard Bureau, said no decision has been made yet about whether to arm the Guardsmen but characterized that possibility as an "ongoing discussion."

"Obviously, we're very concerned that we want our individuals to be have the right to self defense," he said.
