WASHINGTON — Far-right Rep. Majorie Taylor Greene, R-Ga., made good on her threat Wednesday and filed a motion to oust Republican Speaker Mike Johnson, R-La., from power over his decision to pass billions of dollars in military aid for Ukraine.

During the last vote series of the week, Greene stood on the floor and announced she was filing a privileged motion to vacate the speaker’s chair, which will force a vote on Johnson’s future. She was promptly booed by colleagues as she formally announced the effort.

“This is the ‘uniparty’ for the American people watching,” she said in response to the boos, pointing with both hands.

Johnson allies plan to immediately move to “table” or “kill Greene’s vacate motion, two GOP sources said. His GOP allies are in a strong position to beat back Greene’s efforts given that Democratic leaders said on April 30 that their rank-and-file members will help dismiss Greene’s motion to vacate the speaker’s chair.

That would at least temporarily save Johnson’s job, though the fact that Democrats cast votes to keep him in power is sure to infuriate conservative activists and outside groups. And nothing would prevent Greene or any other conservative foe from forcing another vote on Johnson’s fate down the road.

While passionate about toppling Johnson, her campaign never really gained momentum among her colleagues. Conservative Reps. Thomas Massie, R-Ky., and Paul Gosar, R-Ariz., co-sponsored her vacate resolution. And under normal circumstances, those three GOP votes would have been enough to depose Johnson given the GOP’s razor-thin majority and if all Democrats voted to remove him.

But members of both parties are still smarting from the paralysis that took over the House for three weeks last fall after Johnson’s predecessor, Kevin McCarthy, became the first speaker to be ousted from his job in the middle of the congressional term. Greene, a staunch McCarthy ally, vehemently opposed ousting McCarthy and ultimately voted no.

Although he signed on to Greene’s motion to vacate, Massie repeatedly said he didn’t want to force a vote to oust him and cause similar chaos, instead pressing Johnson to resign voluntarily.

Lawmakers, including many conservatives, have said they don’t want a repeat of the fall speaker fight.

The idea of Democrats stepping in to save Johnson began bubbling up over the past several months.

Moderate Democrats publicly and privately said they would vote to save the speaker, especially after Johnson helped stave off a government shutdown, pushed through the renewal of a critical FISA spy tool and passed billions of dollars in foreign aid for Ukraine after months of delays.
