President Donald Trump’s fiscal 2027 budget would slash the Cybersecurity and Infrastructure Security Agency’s total by $707 million, according to a summary released Friday, which would deeply chop down an agency that already took a big hit in Trump’s first year.

Another budget document suggests a smaller — but still substantial — hit of $361 million, with the discrepancy possibly due to the comparison points amid budget uncertainty for CISA’s parent agency, the Department of Homeland Security. DHS and CISA did not immediately respond to a request for clarification.

“At the time the Budget was prepared, the 2026 appropriations bill for the Department of Homeland Security was not enacted, and funding provided by the last continuing resolution it had been operating under (Continuing Appropriations Act, 2026, division A of Public Law 119-37, as amended by division H of Public Law 119-75) had lapsed,” the budget summary notes. “References to 2026 spending in the text and tables for programs and activities normally provided for in the full-year appropriations bill reflect the annualized level provided by the last continuing resolution.”
