Rep. Patrick McHenry, the new speaker pro tempore, is currently occupying the speaker of the House's office in the Capitol. Notably, the sign still reads "Speaker Of The House Kevin McCarthy."

House Majority Leader Steve Scalise has started making the rounds, calling members to see if they would support him if he formally threw his hat in the ring, sources told ABC News.

Rep. Jim Jordan, R-Ohio, who has previously dismissed the idea of wanting to be speaker -- would not rule it out on Tuesday night. Republicans sources close to Jordan say he has started to have conversations about a potential bid.

Another name being floated for the position: Oklahoma Rep. Kevin Hern, the head of the Republican Study Committee.

The House has canceled votes and all remaining legislative business for the week. Republicans plan to gather behind closed doors Tuesday for a candidate forum -- eyeing a vote for speaker as early as Wednesday, sources said.

Republicans have also ordered Rep. Steny Hoyer, D-Md., to vacate his Capitol hideaway office, a source familiar with the communication confirmed to ABC News. Hoyer served for two decades in House Democratic leadership but stepped away after the 2022 midterm elections, stating it was time for a new generation to take over.

Along with the move to push former House Speaker Nancy Pelosi out of her office, it’s the latest sign of how much hostility exists between Republicans and Democrats following the removal of McCarthy as House speaker.

In one of Rep. Patrick McHenry’s first moves as speaker pro tempore, he ordered former Democratic House Speaker Nancy Pelosi to immediately vacate her hideaway office in the Capitol by Wednesday, sources tell ABC News.

Most lawmakers have offices in the buildings surrounding the Capitol -- not in the Capitol itself.

Hideaway offices are private unmarked spaces in the Capitol, typically reserved for members of House leadership. But as a former speaker, Pelosi was allowed to keep one.

Pelosi was informed of this news as she was in San Francisco attending a memorial service for the late Sen. Dianne Feinstein.

In a statement to ABC News, Pelosi criticized the move, “With all of the important decisions that the new Republican Leadership must address, which we are all eagerly awaiting, one of the first actions taken by the new Speaker Pro Tempore was to order me to immediately vacate my office in the Capitol. Sadly, because I am in California to mourn the loss of and pay tribute to my dear friend Dianne Feinstein, I am unable to retrieve my belongings at this time.”

Pelosi continued, “This eviction is a sharp departure from tradition. As Speaker, I gave former Speaker Hastert a significantly larger suite of offices for as long as he wished.”

Politico was the first to report the news.

After Rep. Bob Good, R-Va., delivered a speech castigating McCarthy and explaining why he was joining Gaetz in the motion to vacate, Republican Rep. Tom Cole of Oklahoma spoke out in support of McCarthy and warned of "chaos" should the conference's breakaway faction succeed in removing him.

"They're willing to plunge this body into chaos, and this country into uncertainty, for reasons only they understand," Cole said. To the Democrats who are expected to vote against McCarthy as well, Cole said, "Think long and hard before you plunge us into chaos."

Cole also celebrated how McCarthy had navigated the differences in the closely divided House -- and Washington more broadly -- to notch spending cuts in the debt limit fight earlier this year, pushing back on criticism from Gaetz and others that McCarthy hadn't done enough to curb the federal budget.

Cole also suggested McCarthy had proven himself capable of making sure the House would continue to accomplish Republican priorities.

"I'm very proud of this speaker. I'm very proud to stand behind him. Tomorrow morning, whether I win or lose, I'm going to be pretty proud of the people I fought with and I'm going to be pretty proud of the person I fought for," Cole said.
