Musk in response threatened to decommission SpaceX’s Dragon spacecraft, but later walked it back. The feud began over Musk’s displeasure with the Trump-backed “big, beautiful bill,” which cleared the House last month. The bill would cut electric vehicle credits and could hurt his other company, Tesla.

Elon Musk stepped back from his explosive feud with U.S. President Donald Trump, writing on X that he regrets some of his posts about his onetime ally and that they went “too far.” Early Wednesday morning, he posted “I regret some of my posts about President @realDonaldTrump last week. They went too far.”
