WASHINGTON — Newly empowered House Republicans are preparing to oust Democratic Rep. Ilhan Omar, a Somali-born Muslim lawmaker, from the House Foreign Affairs Committee over her past comments critical of Israel — and as payback after Democrats booted far-right GOP lawmakers from committees for their incendiary, violent remarks.

A procedural vote Wednesday showed unified Republican support for moving against Omar, who has apologized for comments that she has said she came to understand were viewed as antisemitic. It was approved on party lines, with all Democrats opposed. A final vote was expected Thursday.

House Speaker Kevin McCarthy has been eager to flex Republican power to remove the Minnesota Democrat after he blocked Rep. Adam Schiff and Rep. Eric Swalwell, both California Democrats, from rejoining the House Intelligence Committee once the GOP took control of the chamber in January. While appointments to the Intelligence panel are the prerogative of the speaker, the action on Omar would require a House vote.

“This is about vengeance. This is about spite. This is about politics,” said Rep. James McGovern of Massachusetts, the top Democrat on the House Rules Committee, as Republicans called a hurried meeting late Tuesday to consider the move against Omar.

McGovern argued that Democrats had removed Reps. Marjorie Taylor Greene, R-Ga., and Paul Gosar, R-Ariz., from committees for remarks that were far more extreme and violent against fellow lawmakers than those for which Omar had apologized.

Republicans had been waiting for Democrats to formally nominate Omar to the committee, which she served on during the last Congress. Once the committee roster was approved by the House late Wednesday, Republicans signaled they would move to strip her of the seat.

“We’ll have enough votes,” McCarthy assured late Wednesday.

Democrats have little recourse at this point and are planning to formally submit their lineup for a vote. “We are united that she should be seated on the committee,” said Rep. Gregory Meeks of New York, the ranking Democrat on the committee.
