Republicans in the U.S. Congress plan to introduce a sweeping $150 billion defense package that will give an initial $27 billion boost to President Donald Trump’s controversial Golden Dome missile defense shield, according to a document and a congressional aide.

The measure, which will be in addition to the approved $886 billion national security budget for 2025, would also fund the building of 14 warships and lift homeland security spending. It will be part of Trump’s sweeping tax cuts bill, which will cut taxes by about $5 trillion and add approximately $5.7 trillion to the federal government’s debt over the next decade.
