Trump's spending bill includes around $4.9 trillion in tax breaks and increases funding for defense and border security, some of which would be paid for by Social Security cuts. It would also raise the debt ceiling, the limit on how much the federal government can borrow, to $4 trillion.

Donald Trump said on Saturday his relationship with his billionaire donor Elon Musk is over and warned there would be "serious consequences" if Musk funds U.S. Democrats running against Republicans who vote for the president's sweeping tax and spending bill.
