A collection of conservative outside groups is coming to the House Freedom Caucus’ defense after attacks from House colleagues and President Trump over the failure of the Republican leadership’s Obamacare repeal plan.

A Friday conference call featured groups that opposed the Obamacare repeal bill, including Heritage Action, Club for Growth and FreedomWorks. The House leadership pulled the legislation last Friday because of insufficient support. Since the bill’s demise, lawmakers in the Freedom Caucus who opposed the bill have faced attacks from Trump, who tweeted that the group needs to get on board.
