Several members of the House Freedom Caucus have already lined up their opposition to the House Republican leadership-endorsed Senate budget resolution. The Senate budget resolution would only need a few Republican detractors to tank it altogether.

House Budget Committee Chair Jodey Arrington (R-Texas) on Saturday blasted the Senate’s budget resolution, passed by the upper chamber only hours before, as “unserious and disappointing.”

The latest proposal combines key components of the House and Senate blueprints, with GOP leaders hoping to advance the instructions before adjourning for Easter recess.
