House Republican leaders are scrambling to shore up support for President Trump's massive domestic policy bill amid pushback to the Senate's changes, as the GOP seeks to approve the final version of the legislation ahead of a July 4 deadline to get the bill to the president's desk.

Senate Republicans narrowly approved President Donald Trump’s sweeping tax and spending cuts package Tuesday after a dayslong grind to secure the support of key holdouts.
