Rep. Jim Jordan (R-Ohio) failed to gain the required number of votes Tuesday to become House speaker on the first ballot.

The founding member of the House Freedom Caucus needed 217 votes to clinch the gavel, but had to sweat to get to 200 votes — as 20 members of the Republican conference opted to back other colleagues.

House Minority Leader Hakeem Jeffries (D-NY) received all 212 votes from a united Democratic conference.

Of the 20 Republican dissenters, seven stood with Majority Leader Steve Scalise (R-La.), whose own bid for the speakership flopped after one day of conference meetings and was never put to a floor vote.

Another six stood by ousted former Speaker Kevin McCarthy (R-Calif.) while a trio of New Yorkers put in the name of former congressman and 2022 gubernatorial candidate Lee Zeldin.

Single votes were cast for Reps. Mike Garcia (R-Calif.), Majority Whip Tom Emmer (R-Minn.), Rules Committee Chairman Tom Cole (R-Okla.) and Thomas Massie (R-Ky.)

Rep. Tom Kean Jr. (R-NJ) was one of the last Republicans to register support for Jordan ahead of the vote, along with Rep. Brian Fitzpatrick (R-Pa.), who in a statement also denounced the “208 aiders and abettors” in the Democratic caucus “who enabled the 8 extremists to punish bipartisanship” in the House.

“Can any of my 216 colleagues who votes to vacate Speaker McCarthy honestly say that if Hamas Had attacked Israel the day before the Motion to Vacate vote, that they still would have voted to remove Speaker McCarthy?” he asked.

Fitzpatrick nevertheless said that Republicans “must elect a Speaker and re-open the government ASAP,” citing Americans held hostage by Hamas terrorists, the war in Ukraine and a potential invasion of Taiwan by Chinese forces.

Members skeptical of Jordan raised the issue of security funding for Ukraine and Israel amid ongoing wars as well as the need to pass further government funding by Nov. 17 among their concerns.

Jordan allies worked the phones and social media over the weekend and through Monday in an effort to flip some of the final “no” votes but were ultimately unsuccessful.

House GOP aides who spoke with The Post were uncertain whether the Ohio Republican’s strategy to bring the deliberations out in the open would force some lawmakers to switch on subsequent ballots.

But another aide predicted once the roll call vote hit four “nos” that “a lot more” House Republicans would join in the effort to tank Jordan.

Rep. Gus Bilirakis (R-Fla.) was the lone Republican lawmaker missing from the House vote, meaning 220 Republicans and 212 Democrats were present for the first vote.

Jordan, who chairs the House Judiciary Committee, has vowed to stand for as many ballots as it takes to win the gavel.
