Donald Trump’s $3.3 trillion tax and spending cut bill passed the Senate Tuesday after a furious push by Republican leaders to persuade holdouts to back the legislation and hand the president a political win.

Party leaders were able to muscle through considerable internal rifts, but the bill’s fate in the House was uncertain.

The revised package now heads back to the House, where Republican leaders are hoping to approve it and send it to Trump before a self-imposed July 4 deadline. But it faces hurdles.
