In the eve of an expected vote, the Ohio congressman said he felt “really good” about securing the 217 supporters he needs.

Jordan, a founding member of the ultra-conservative House Freedom Caucus, appears to be gaining support from former foes.

As of Monday, fewer than 10 Republicans refused to support his candidacy, down from more than 50 on Friday.

The number of remaining no-votes is unclear, but the chairman of the House Judiciary Committee cannot afford to lose four Republicans.

Almost two weeks have passed since the House ousted its Speaker. Congress’ lower chamber is unable to perform its most basic functions due to the vacuum at the top of the government. Jordan has the support of many conservative Republicans and counts former President Donald Trump as an ally.

Several moderate lawmakers had previously expressed reluctance to support him. On Monday, a few of them reversed course and endorsed Mr Jordan, including Missouri’s Ann Wagner and Alabama’s Mike Rogers.

Mr Rogers, chairman of the House Armed Services Committee, wrote on social media that the two have “cordial, thoughtful and productive conversations over the past two days” and eventually come to an agreement on several policy issues. Mr Rogers reportedly said last week that Mr Jordan had little he could do to sway him.

Mr Jordan vowed to unite his party on Monday, scrambling to consolidate support a day before the expected vote on the floor.

In his letter, he wrote, “We Republicans are far more united than we are divided.”
