Marjorie Taylor Greene wants Speaker Mike Johnson out

Congresswoman Marjorie Taylor Greene has had enough of Speaker of the House Mike Johnson. Now she has taken the first procedural step to force a vote on whether to oust him.

As the House of Representatives was voting to approve a $1.2tn (£950bn) spending package that would avert a partial government shutdown at midnight, the Georgia Republican filed a "motion to vacate" with the chamber's clerk.

If she takes the next step and formally introduces the measure, the House could vote on Mr Johnson's fate within days.

The Louisiana congressman won the speaker's job last October after the previous Speaker, California Congressman Kevin McCarthy, was ousted through a similar tactic.

There were weeks of acrimony before he took up the gavel, as several more prominent Republicans tried and failed to secure enough support to win a majority in the chamber.

On Friday, more than 100 Republicans voted against the spending bill backed by Mr Johnson and other Republican leaders.

A group of hard-core conservatives, including Ms Greene, objected to the amount of funding authorised, a lack of sweeping changes to US immigration policy and several provisions supporting healthcare clinics that perform abortions.

Ms Greene, speaking on the steps of the US Capitol after the spending vote, said that Mr Johnson had "betrayed" Republicans.

She said she did not want to throw the House into chaos, but that she would move forward with her motion to vacate if House Republicans did not find a new leader.

At the moment, however, the Georgia Republican appears to have little support within her own party for the move.

Florida Republican Matt Gaetz, who led the push to oust Mr McCarthy, said that this latest effort could ultimately lead to a Democratic speaker, perhaps with the backing of centrist Republicans.

Speaking to reporters at the Capitol, Republican Congressman Mike Lawler called the move "idiotic" and said it harms conservative priorities and the nation as a whole.

Meanwhile, some Democrats have expressed reluctance to help trigger another House power struggle.

If Ms Greene is only able to convince a handful of Republicans to go along with ousting Mr Johnson, it would require near unanimous Democratic approval for that vote to pass.

Democrats provided that support last year to remove Mr McCarthy, who many had viewed as operating in bad faith. Mr Johnson, who negotiated with Democrats to craft Friday's government spending package, has not engendered such ill will.

The House of Representatives will break for its two-week Easter recess on Friday, which means no action can be taken on Ms Greene's motion until the legislators return to Washington.

That affords House Republican wary of another leadership fight more time to try to convince the Georgia congresswoman not to light the fuse on the political bomb she just unveiled.
