WASHINGTON—The House narrowly passed Republicans’ sprawling tax-and-spending bill, delivering a major second-term victory for President Trump and again demonstrating his power to keep GOP lawmakers in line.

The procedural "rule" vote was 219-213, with one Republican, Rep. Brian Fitzpatrick of Pennsylvania, joining all Democrats in opposition. At one point, five Republicans had voted "no" on the rule, while eight others did not vote, but Speaker Mike Johnson, R-La., managed to sway them overnight.
