A top Trump aide warred on Twitter Saturday with a conservative Michigan congressman and Freedom Caucus member.

“@realDonaldTrump is bringing auto plants & jobs back to Michigan,” Trump senior adviser Dan Scavino tweeted in a direct shot at GOP Rep. Justin Amash. “@justinamash is a big liability. #TrumpTrain, defeat him in primary.”

Amash, a vocal opponent of the GOP’s failed health-insurance bill, fired back: “Trump admin & Establishment have merged into #Trumpstablishment,” he wrote. “Same old agenda:
Attack conservatives, libertarians & independent thinkers.”
