Elon Musk seemed kinda mad Tuesday ― and the internet couldn’t have been happier. President Donald Trump’s former adviser for the unofficial Department of Government Efficiency took to his X social media platform to gripe about the passage of the president’s so-called Big Beautiful Bill,

"Shame on those who voted for it: you know you did wrong," the Tesla CEO wrote, citing projections that the legislation would add more than $2 trillion to the national debt.

The bill calls for an extension of Trump’s tax cuts from 2017, while also putting in tax breaks for tips and overtime. The bill also earmarks more money for Trump’s plan on deporting illegal immigrants, as well as overhauling Medicaid and food stamps.
