President Donald Trump warned Republicans on Wednesday that failure to pass his massive tax and immigration package would be “ultimate betrayal.” In a statement, the White House said the bill needs to “pass immediately” to keep promises that Trump and fellow Republicans made while campaigning.

US President Donald Trump’s signature tax bill narrowly passed the House on the morning of May 22, overcoming fierce Republican infighting and advancing a sprawling multi-trillion dollar package that would avert a year-end tax increase at the expense of adding to the US debt burden.

U.S. Senate Republicans said on Thursday they will seek substantial changes to President Donald Trump's sweeping tax and spending bill after it narrowly won approval in the House of Representatives, in a sign that significant hurdles remain for the package.
