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 debate within President Donald Trump 's Republican Party over a massive tax-cut and spending bill returns to the House of Representatives on Wednesday. The Senate passed the legislation by the narrowest possible margin on Tuesday. Nonpartisan analysts say it will add $3.3 trillion to the nation's debt over the next decade.
