After declaring he was stepping away from the political spotlight, Elon Musk got right back in it. As the Senate debated President Donald Trump’s “Big, Beautiful Bill” on Monday before a final vote, Musk issued a stark warning via his social media platform X.

Musk’s harsh criticism comes as senators are continuing to vote on an unlimited number of amendments, known as a “vote-a-rama,” to the GOP’s sweeping domestic policy megabill, which first passed the Senate over the weekend. In a 51-49 vote, only two Republicans — Sens. Rand Paul (R-Ky.) and Thom Tillis (R-N.C.) — joined Democrats in opposition.

As Musk renewed his attacks on the “One, Big, Beautiful Bill,” Trump remained unusually civil, calling his former pal a “wonderful guy.”
