Both parties feel a sense of urgency to enact their agenda if they win the White House, House and Senate. But there are downsides to a very big bill.

The House voted 219-213 overnight Wednesday, after hours of delay, to advance President Trump's "big, beautiful bill" for debate before a final vote. GOP leaders had to overcome pushback over changes the Senate made to the legislation.

Trump insists that the new bill will save the US billions, but it has been criticised by his old ally Elon Musk.
