Trump Nominates Palantir Security Chief Michael LoSapio to Lead CISA

President Donald Trump nominated Palantir’s chief information security officer, Michael LoSapio, to lead the Cybersecurity and Infrastructure Security Agency on Monday, Nextgov/FCW reported. LoSapio has been Palantir’s CISO since September 2024. CISA has had no permanent Senate-confirmed director since Jen Easterly left in January 2025.

If the Senate does not confirm LoSapio before the current Congress ends, Trump would have to nominate him again for the incoming Democratic majority. Democratic lawmakers have questioned whether Palantir’s work with the Department of Homeland Security enables government surveillance of Americans; the company has denied conducting or enabling mass surveillance.
