Senate Republicans adopted a fiscal blueprint Saturday for President Donald Trump’s “one big, beautiful bill.” What comes next is anyone’s guess.

The Senate voted 51-48 on a budget resolution that unlocks their ability to pass a party-line bill later this year that will combine an overhaul of the tax code with border, energy and defense policies. GOP Sens. Susan Collins of Maine and Rand Paul of Kentucky joined all Democrats and independent in opposing the resolution — though other Republicans still have concerns that will need to be addressed before passing the final bill.
