President Donald Trump is asking Congress to slash $163 billion in overall spending in his budget proposal. Here’s what to know.

Trump’s budget generally left the Treasury Department alone — except for the IRS. The budget seeks to cut IRS funding by $2.5 billion. The agency has already frozen hiring, initiated broad-based layoffs and paused a Biden-era technology modernization process under the direction of officials from the U.S. DOGE Service.

A draft budget proposal circulating among federal officials would dramatically deepen cuts at the nation’s top health agency, eliminating some public health programs entirely and serving as a roadmap for more mass firings.
