"If the Republican conference can't find a way forward, then unfortunately a discharge petition is a possibility," Zinke added.
Between the lines: Underpinning the threat is a belief from some GOP lawmakers that Ukraine's war effort could collapse if aid isn't sent soon. "A lot of people look at it and go, 'we could lose a war,'" Zinke said.

Rep. Joe Wilson (R-S.C.) signed onto a letter with 90 Democrats on Monday calling for a vote on the Senate bill.
