President Donald Trump’s nomination of Palantir chief information security officer Michael LoSapio to lead the Cybersecurity and Infrastructure Security Agency is already facing scrutiny from senior congressional Democrats, who say his ties to the government technology contractor could complicate efforts to rebuild the agency.
The White House submitted LoSapio’s nomination to the Senate on Nov. 9, naming him to succeed former CISA Director Jen Easterly, who resigned in January 2025. [16] LoSapio has served as Palantir’s CISO since September 2024, after previously leading the company’s infrastructure and network security organization, according to Defense One.
CISA has operated without a Senate-confirmed director throughout Trump’s second term. Nick Andersen, the agency’s deputy director, is serving as acting director, according to CISA. The vacancy comes as the agency works through staffing and budget reductions while retaining responsibility for federal civilian network defense and coordination with owners of critical infrastructure.
Sen. Maggie Hassan, D-N.H., who is expected to chair the Senate Homeland Security and Governmental Affairs Committee when Democrats take control in 2027, said LoSapio’s senior role at Palantir raised questions about his independence and judgment. Rep. Bennie Thompson, D-Miss., the expected incoming chairman of the House Homeland Security Committee, similarly urged senators to examine Palantir’s role in Department of Homeland Security surveillance programs before advancing the nomination, CyberScoop reported.
The concerns center on potential conflicts involving Palantir’s work for DHS and its Immigration and Customs Enforcement component. Patrick Eddington, a senior fellow at the Cato Institute, told CyberScoop that senators should examine LoSapio’s Palantir holdings, any divestiture plans, the length of proposed recusals and whether he has arrangements to return to the company after government service. A Palantir spokesperson did not respond to requests for comment.
Supporters of the nomination point to LoSapio’s technical background and experience defending a company that handles sensitive government-related work. A cybersecurity executive who has worked with him described him as a highly capable, politically independent practitioner, while former CISA adviser Joshua Corman said the confirmation process could consume valuable time and urged the next director to build on Andersen’s work.
The Senate could consider the nomination during its lame-duck session, but a crowded calendar creates uncertainty. If lawmakers do not act before the current Congress ends, the administration would need to resubmit LoSapio’s nomination to the incoming Democratic-controlled Senate, where his Palantir connection is likely to receive even closer examination, according to Cybersecurity Dive.
