On Monday, Warren posted a tweet from Congressional Progressive Caucus Chair Pramila Jayapal, a Democrat from Washington, that contended it was “‘TIME’ for Elon Musk to pay his fair share of taxes.” The senator responded that she had “a plan for that.”

Earlier this year, Warren, Jayapal and Pennsylvania Representative Brendan Boyle introduced the Ultra-Millionaire Tax Act, a proposal that would place a 2 percent annual tax on households with a net worth above $50 million and a 3 percent annual tax on households with net worths above $1 billion.
