Dan Scavino, a senior aide to President Donald Trump who manages Trump's social media, attacked Rep. Justin Amash (R-Mich.) on Twitter Saturday and called for him to be primaried in next year's election.
".@realDonaldTrump is bringing auto plants & jobs back to Michigan," Scavino tweeted after noon on Saturday. "@justinamash is a big liability. #TrumpTrain, defeat him in primary."
Scavino's tweet came from his personal Twitter account and not his official Trump administration account.
The tweet comes as the Trump administration continues to attack the House Freedom Caucus, the conservative wing of House Republicans, which Amash is a member of. Trump has accused the Freedom Caucus of sinking his recent effort to repeal Obamacare after most members refused to support the GOP bill.
Caucus members said they wouldn't support it because it was essentially a watered-down version of Obamacare and because passing the bill wouldn't fulfill their promise to fully repeal Obamacare and replace it with a market-based solution.
Trump began singling out the Freedom Caucus on Twitter last Sunday:
He followed it up on Monday with:
And on Thursday he said that the Freedom Caucus needs to get "onboard" with his agenda — while urging his supporters to "fight" House conservatives in 2018:
In subsequent tweets on Thursday, Trump singled out Reps. Mark Meadows (R-N.C.), Jim Jordan (R-Ohio) and Raul Labrador (R-Idaho) for not being "onboard" with his agenda.
Trump was subsequently criticized by some of his staunchest supporters, like Fox News host Sean Hannity and conservative radio host Laura Ingrahm, for targeting conservatives. He also drew the ire of Amash.
Responding to Trump's tweet about trying to unseat Freedom Caucus members in 2018, Amash said: "It didn't take long for the swamp to drain @realDonaldTrump. No shame, Mr. President. Almost everyone succumbs to the D.C. Establishment."
And in reply to Scavino on Saturday, Amash continued to say he believes the Trump administration has already become part of the entrenched Washington establishment. He even gave the Trump administration a new nickname.
"Trump admin & Establishment have merged into #Trumpstablishment. Same old agenda: Attack conservatives, libertarians & independent thinkers," Amash wrote.
