The Homeland Security secretary said the Trump administration plans to refocus and rebuild CISA even as the agency has lost roughly a third of its staff and faces proposed budget cuts. Secretary Markwayne Mullin told lawmakers CISA now has about 2,200 personnel and likely needs about 2,800, while the White House's fiscal 2027 budget would cut more than $700 million. He also signaled a new nominee to lead CISA and defended assigning Treasury a lead role in an AI vulnerability clearinghouse created by the new executive order.
Why it matters: CISA is the main federal agency that helps defend civilian networks, coordinate with private companies, and warn about major cyber risks, so sharp cuts or mission changes can affect incident response and national cyber preparedness. This matters to defenders, state and local governments, and the public because it signals potential changes in federal cyber support, vulnerability handling, and long-term staffing capacity.
