The tech tycoon had said Trump's bill would increase the deficit and undermine the work of Department of Government Efficiency (DOGE), which has fired tens of thousands of people.
Musk -- who was a constant presence at Trump's side before pulling back to focus on his Space X and Tesla businesses -- also complained that DOGE had become a "whipping boy" for dissatisfaction with the administration.
"I was disappointed to see the massive spending bill, frankly, which increases the budget deficit, not just decreases it, and undermines the work that the DOGE team is doing," Musk said in an interview with CBS News.
Trump's "One Big, Beautiful Bill Act" -- which passed the US House last week and now moves to the Senate -- offers sprawling tax relief and spending cuts and is the centerpiece of his domestic agenda.
