House Republicans began taking a key procedural vote on President Trump's massive domestic policy bill late Wednesday evening, after scrambling for hours to shore up support ahead of a self-imposed July 4 deadline to get the bill to the president's desk.

The “big, beautiful bill” is largely a tax reform bill, wrapped around other Trump priorities, being shuttled through Congress through a strict budget process called “reconciliation.”

By Wednesday evening, enough Republicans remained opposed to the Senate’s version of the bill to effectively stall its passage in the House.
