WASHINGTON (AP) — Jubilant Republicans pushed on early Wednesday to the verge of the most sweeping rewrite of the nation's tax laws in more than three decades, a deeply unpopular bill they insist Americans will learn to love when they see their paychecks in the new year. President Donald Trump cheered the lawmakers on, eager to claim his first major legislative victory.

After midnight, the Senate narrowly passed the legislation on a party-line 51-48 vote. Protesters interrupted with chants of "kill the bill, don't kill us" and Vice President Mike Pence repeatedly called for order. Upon passage, Republicans cheered, with Treasury Secretary Steve Mnuchin among them.

Senate Majority Leader Mitch McConnell, R-Ky., insisted Americans would respond positively to the tax bill.

"If we can't sell this to the American people, we ought to go into another line of work," he said. Trump hailed the vote in an early morning tweet and promised a White House news conference, likely Wednesday, when the House completes legislative action on the measure.

The early morning vote came hours after the GOP rammed the bill through the House, 227-203. But it wasn't the final word in Congress because of one last hiccup.

Three provisions in the bill, including its title, violated Senate rules, forcing the Senate to vote to strip them out. So the massive bill was hauled back across the Capitol for the House to vote again on Wednesday, and Republicans have a chance to celebrate again.
