House Freedom Caucus
House Freedom Caucus is an 'invite-only' group, the conservative version of the much larger Republican Study Committee in the U.S. House of Representatives. Their membership will often clash with GOP leadership over various important issues.
House Freedom Caucus mission reads,
"The House Freedom Caucus gives a voice to countless Americans who feel that Washington does not represent them. We support open, accountable and limited government, the Constitution and the rule of law, and policies that promote the liberty, safety and prosperity of all Americans."
