President Donald Trump’s tax cut wish list would cost would the federal government between $5 trillion and $11.2 trillion in lost revenue over the next decade, according to a new analysis from a budget watchdog group.

The House GOP wants what Trump has called a “big, beautiful bill” that would extend some $3 trillion in tax cuts that expire at the end of the year, and include a list of other GOP priorities, including funding for the president’s mass deportation effort and border wall.
