Twitter CEO Elon Musk didn’t hold back any punches after saying the Biden administration could “weaponize” federal agencies against Twitter if former President Donald Trump returned to the platform.

“Will be interesting to see how the Biden administration reacts to this,” Musk tweeted Wednesday. “They may try to weaponize Federal agencies against Twitter.”

Musk’s post was in response to a user’s tweet regarding Trump’s rumored return to Twitter and Facebook following his lengthy ban from the platforms.

According to NBC News, Trump’s presidential campaign asked Facebook’s parent company, Meta, to grant him access to his social media accounts.

Trump’s Twitter account was shut down following the US Capitol riot in Jan. 2021. Musk restored Trump’s personal Twitter account on Nov. 19 after he conducted a public poll.
