Who's in the House Freedom Caucus? Here's a list of Republicans in the group.

Impact

On Friday morning, Republican leadership was still scrambling to whip up votes needed to pass their doomed health care bill, the American Health Care Act.

The legislation, which President Donald Trump endorsed as a conservative alternative to former President Barack Obama's Affordable Care Act, was struggling to attract GOP support. Some feared the bill's cut to Medicaid funding would have a negative impact on constituents; others worried it wasn't conservative enough.

Chief among the hardliners were the members of the House Freedom Caucus, the far-right group of three dozen conservative lawmakers known for stirring up trouble, even among their own ranks.

Despite reports that House Speaker Paul Ryan — and Trump himself — personally appealed to Freedom Caucus members in an effort to lock in the required votes, the lawmakers refused to play ball. By Friday afternoon, GOP leadership was forced to pull the bill in disgrace after failing to drum up support.

Below are all 30 known members of the House Freedom Caucus, some of whom are the chief players responsible for defeating Trump in his first attempt at passing major legislation.
