Just to bring you up to speed the Freedom Caucus is the latest iteration of the Tea Party that Sarah Palin helped to popularize way back in 2009.The Freedom Caucus will hurt the entire Republican agenda if they don't get on the team, & fast. We must fight them, & Dems, in 2018!— Donald J. Trump (@realDonaldTrump) March 30, 2017
These are the hard right conservatives that Trump aggressively pursued during his campaign, and who turned out in large numbers to vote for him.
These folks have no intention of "getting on the team" and in fact would rather disassemble the team and start a new hard right version of their own.
Picking a fight with them will all but ensure that Trump never gets anything done.
