Trump amplified his comments in a post on his Truth Social network later Sunday, saying he was “saddened to watch Elon Musk go completely ‘off the rails’” over the past five weeks. Trump also touted his budget package that “unfortunately for Elon” eliminates the electric vehicle subsidy.

"When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy," Musk said in the announcement.
