Republicans have officially secured control of the House of Representatives, giving President-elect Donald Trump a Republican "trifecta" to pursue his agenda for at least two years.

But some House Republicans are threatening to open up a fresh divide in the party's narrow majority by opposing Speaker Mike Johnson (LA), Politico reported.

Johnson facing new threats

Johnson, a Trump ally, has faced skepticism and pushback from right-wing Republicans who have questioned his commitment to shrinking the size of government.

Similar grievances led a small group of Republicans to throw out Johnson's predecessor, Kevin McCarthy, in a historic vote that divided the Republican conference.

While Johnson has largely quieted opposition within his ranks, some remain skeptical of him ahead of a preliminary leadership vote Wednesday.

Many of the holdouts are aligned with the House Freedom Caucus, which has continually caused trouble for House leadership over the last couple of years.

According to Politico, some members may challenge Johnson during the secret ballot Wednesday, although it's unclear exactly what they will do. If Johnson runs unopposed, leadership could call a voice vote, undercutting any effort to oppose him until the floor vote in January.

“There are a number of members who are still very undecided and withholding judgment,” said one GOP member.

Undermining trifecta?

The holdouts want firm commitments to reduce federal spending and to reform House rules. In particular, they want to preserve a controversial rule allowing one member to trigger a vote to remove the Speaker.

McCarthy agreed to that rule - which ultimately led to his downfall - to secure support during his marathon nomination battle, which lasted 15 rounds.

While Johnson is expected to win the secret ballot this week, the real test for Johnson comes in January, when he'll face a floor vote.

He may be in a safer position than McCarthy, Politico noted. Whereas Republicans only had control of the House during the McCarthy saga, President-elect Trump is heading back to the White House with Republican majorities in the House and the Senate.

While the rebels see themselves as holding leadership accountable, others may view their efforts as helping to squander a historic opportunity to pass Trump's agenda.

An attempted repeat of the chaos that played out in 2023 could face a sharp response from President Trump himself, who is not one to stay quiet when someone is standing in his way.
