A small but significant number of moderate GOP lawmakers are plotting a path toward potentially working with Democrats to fund the government past Sept. 30 and combat a shutdown.

At least three Republicans — Reps. Mike Lawler (N.Y.), Don Bacon (Neb.) and Brian Fitzpatrick (Pa.) — have expressed an openness to joining Democrats in signing a discharge petition, a mechanism to force a vote on a measure against the wishes of the Speaker.

Four members of the bipartisan Problem Solvers Caucus introduced a bill Friday that reflects the group’s framework for a short-term stopgap funding measure. Fitzpatrick suggested Sunday that lawmakers could use a discharge petition to compel a vote on that legislation.

Five Republicans would need to join their party’s leaders in order to force action with Democrats.
