Senate Majority Leader John Thune can afford to lose three Republican senators and still pass the bill, and there are more than that, right now, who have problems with it. Like the House, he will have to balance the concerns from moderate and conservative members of his conference.

The tax cut package that passed the U.S. House and President Trump has dubbed the "big, beautiful bill" may change before it becomes law.

The House passed the “Big Beautiful Bill Act” in the wee hours of Thursday after more than seven hours of debate on the floor — and that doesn’t include the nearly 22-hour hearing beforehand that lasted the entirety of Wednesday.
