Among the committees was the Cyber Safety Review Board that was conducting an investigation into the hack of American telecom companies by Beijing actors dubbed "Salt Typhoon."

House Committee on Homeland Security Chairman Mark Green (R-Tenn.) told Nextgov/FCW that "President Trump's new DHS leadership should have the opportunity to decide the future of the Board. This could include appointing new members, reviewing its structure, or deciding if the Board is the best way to examine cyber intrusions."

DHS terminates advisory committees, including CSRB, halting investigations into Chinese cyberattacks and AI safety.

The board had gained notoriety after investigating major hacking incidents including the Log4Shell vulnerability, the hacking group Lapsus$, and the compromises of Microsoft Exchange inboxes in 2023. The board was investigating the CCP-backed Salt Typhoon, a hacking group that compromised major telecom companies in the past few years.

The Department of Homeland security told members of the Cyber Safety Review Board that their membership was terminated.
