The band of roughly 30 hard-liners, which includes some of President Donald Trump’s top allies on Capitol Hill, cited fiscal concerns in a statement opposing the agreement. The deal would lift stiff budget caps and raise the debt ceiling for two years, raising federal spending by a total of $320 billion without being fully offset.

“The House Freedom Caucus has grave concerns about this budget agreement and will oppose it on the House floor,” the group said. “Our country is undeniably headed down a path of fiscal insolvency and rapidly approaching $23 trillion in debt. This is completely unsustainable, and we owe taxpayers and future generations better.”

“All sides should go back to the drawing board and work around the clock, canceling recess if necessary, on a responsible budget agreement that serves American taxpayers better—not a $323 billion spending frenzy with no serious offsets,” the group added.
