The Speaker has promised to push forward with a Ukraine aid package once the House returns from a two-week break.

Representative Don Bacon acknowledged Sunday that it is “possible” that Speaker Mike Johnson will lose the top House job over an impending vote on aid to Ukraine. “I’m not going to deny it,” the Nebraska conservative told NBC’s Kristen Welker.

The comment comes as the House enters the second half of a two-week recess, which came on the heels of a tense fight over a government funding bill that barely averted a shutdown. Johnson entered the break promising to “turn our attention” to Ukraine, an issue that has divided the fractious House GOP caucus and kept the U.S. government from approving an aid package, even as the Senate passed a $95 billion bill in February.

George Representative Marjorie Taylor Greene, who has long been staunchly opposed to U.S. aid to Ukraine, filed a motion to vacate Johnson’s speakership right as the House went into recess, warning that Johnson “should not bring funding for Ukraine” to the House floor. Greene has yet to say when she plans to move forward with the motion.
