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 218-214 vote Thursday sends the measure to Trump’s desk, ahead of the July 4 target he set for Congress to finish the legislation that cuts taxes, boosts border security and lowers social safety-net spending. Trump and GOP leaders muscled the bill through the House after an all-night session, despite many lawmakers’ misgivings about the version the Senate passed 51-50 earlier this week.
