WASHINGTON — House Republican leaders moved Wednesday to try to pass the party's massive domestic policy package after the Senate approved it, launching a full-court press and enlisting the help of President Donald Trump to sway a broad group of holdouts.

President Trump has been urging lawmakers to send him the bill to sign into law by July 4, but also acknowledged the timeline is flexible.

Many Republican hardliners spoke to Trump and flipped to yes without rewrites to his signature legislation, but the final vote is expected to be close.

Donald Trump's signature tax and spending bill was in limbo early Thursday as Republican leaders in the US Congress scrambled to win over a group of rebels threatening to torpedo the centerpiece of the president's domestic agenda.

Republicans in the House of Representatives on Wednesday struggled to pass President Donald Trump's massive tax-cut and spending bill as a handful of hardliners withheld their support over concerns about its cost.
