WATCH LIVE: Greene vs. Johnson. House of Representatives returns to session

Speaker Mike Johnson (R-La.) is facing a gauntlet when Congress returns today, where the GOP leader will seek to usher another round of aid for Ukraine — as well as Israel, Taiwan and border security — through his rebellious conference while a motion to remove his gavel hangs like an anvil over the debate. But the foreign aid portions of that proposition have grown increasingly unpopular within his conference, and Rep. Marjorie Taylor Greene (R-Ga.) has already unveiled a motion-to-vacate resolution, all but daring the Speaker to put Ukraine aid on the floor so she can force a vote on his ouster.

“Funding Ukraine is probably one of the most egregious things that he can do,” Greene told CNN in an interview last week.

Senate Republicans want Johnson to stand up to the “chaos caucus” in the House GOP conference, warning that time is running out on the battlefront in Ukraine, The Hill’s Alexander Bolton reports. Sen. Roger Wicker (Miss.), the ranking Republican on the Senate Armed Services Committee, acknowledged the Speaker faces a difficult situation, but he predicted he would survive any motion advanced by Greene or another conservative rebel to oust him.
