Musk had previously criticized the Republican tax and spending bill before he made nice with President Trump. Now he's back to criticizing.

ToplineThe Senate is slated to vote on President Donald Trump’s budget and spending bill Saturday, as Republicans seek to push the controversial measure through by July 4 despite some opposition within the GOP and from former Trump adviser Elon Musk.

Musk has previously made his opinions about Trump's "big, beautiful bill" clear. In late May, just a few days before he officially left his post in the federal government, he told "CBS Sunday morning" he was "disappointed" with the bill's price tag.
