Department of Homeland Security Secretary Markwayne Mullin told Congress Wednesday that the Cybersecurity and Infrastructure Security Agency would ideally have 2,800 personnel, up from approximately 2,200 now and down from 3,400 before the second Trump administration began.

President Donald Trump has pushed to dramatically reduce personnel numbers at the agency, something that has drawn criticism from both Democrats and Republicans on the Hill. Trump has proposed hundreds of millions more in cuts for fiscal 2027.

House Homeland Security Committee Chairman Andrew Garbarino, R-N.Y., asked Mullin at a hearing Wednesday about further proposed CISA budget cuts, saying he was “concerned” about personnel numbers and funding for education programs and whether the fiscal 2027 blueprint would “negatively impact those efforts.”

Mullin said DHS funding lapses have made the department rethink CISA, although the deep CISA personnel reductions predate the recent spate of government shutdowns. 

“We had to readjust the way we’re looking at CISA and better lean on public partnerships,” he said. The agency can work well with 2,800 people “If we can actually have the partnerships we need with states and be able to use the grants, the monies that [we] saved with CISA to be able to invest with local and state municipalities. … We’re not going to fail on the mission we have in front of us.”

CISA personnel figures are in a constant state of flux. The CISA staff figure of 2,200 Mullin gave is down even from December. In March, acting director Nick Andersen said CISA was looking to hire 300 people.

There’s been no proposal from the Trump administration to-date to take funds formerly allocated to CISA and shift them to state governments for cybersecurity. State officials have said CISA budget cuts have made their jobs harder, and most experts have said the Trump administration’s approach to shift cyber responsibilities to states is badly misguided.

Congress has yet to permanently reauthorize the State and Local Cybersecurity Grant Program that expired last year before it got a temporary extension and is due to expire again in September.

CISA has gone without a Senate-confirmed director for the entirety of the second Trump administration. Mullin said “we’ve got a person soon to be nominated that will be running CISA that has the ability to recruit and focus on the authorities we have.”

Mullin said CISA has “unique” authorities that haven’t “been completely utilized.” 

“We want CISA to be the leader in cybersecurity,” he said. “They should be and they will be.”

A House Appropriations subcommittee is set to consider a DHS funding bill Friday.
