“[email protected] is bringing auto plants & jobs back to Michigan. @justinamash is a big liability. #TrumpTrain, defeat him in primary,” Scavino wrote.

But that tweet, sent from Scavino’s personal Twitter account, immediately landed him in controversy as ethics lawyers called out Scavino for possibly violating the Hatch Act, a Depression-era law that regulates campaigning by government officials.

“Look at the official photo on this page. Read the Hatch Act and fire this man NOW. Someone call OSC,” Richard Painter, the former ethics attorney in the George W. Bush White House, wrote on Twitter, referring to the Office of Special Counsel, the independent agency charged with monitoring and enforcing the law.
