Workers at the Social Security Administration’s office in Birmingham were “unjustly terminated” by Elon Musk’s Department of Government Efficiency, U.S. Rep. Terri Sewell said Tuesday, as the congresswoman called out the billionaire’s “reckless power trip.”

Sewell initially tweeted Tuesday that her office “received reports that more than 100 of my constituents who work at the Social Security Administration in Birmingham have been unjustly terminated,” but later clarified that the American Federation of Government Employees — the union representing federal workers — told her the cuts affected “Social Security Region 4, which covers several states including Alabama.”

“We are working to determine exactly how many employees in Alabama’s 7th Congressional District have been impacted, but our office has heard from constituents today who lost their jobs,” the congresswoman posted. “We will continue to monitor the situation closely.”

In her initial tweet, Sewell said Musk’s effort to root out government waste is causing damage to working people in her district, including those employed by the Social Security Administration Office at 1200 Rev. Abraham Woods Blvd. in Birmingham.

“Elon Musk’s reckless power trip is directly threatening the livelihoods of my constituents,” the congresswoman tweeted. “This madness must stop!
