The US House of Representatives pushed through Trump’s massive legislative package early Thursday after nearly 24 hours of nonstop pressure, backroom deals, and public fighting. The final 218-214 vote locked in Trump’s biggest policy win since returning to the White House.

Republican leaders barely scaled a key procedural hurdle to bring up the bill, but Democrats delayed its consideration and it was unclear whether the G.O.P. had the votes to pass it.

After days of negotiations and last-minute dealmaking, the US Congress passed a multitrillion-dollar tax and spending bill securing President Donald Trump’s domestic policy agenda.
