Former President Donald Trump on Friday called on Microsoft to terminate Lisa Monaco, the company’s President of Global Affairs and a former U.S. Deputy Attorney General, citing what he described as serious national security risks.

In a post to his Truth Social platform, Trump accused Monaco of compromising U.S. security and claimed she had been stripped of her security clearances and barred from federal facilities. The remarks came just one day after Trump-aligned prosecutors secured the indictment of former FBI Director James Comey, a development Trump had publicly pushed for.

“She is a menace to US National Security, especially given the major contracts that Microsoft has with the United States Government,” Trump wrote. “Because of Monaco’s many wrongful acts, the US Government recently stripped her of all Security Clearances, took away all of her access to National Security Intelligence, and banned her from all Federal Properties.”

Trump provided no evidence to support the claims, and neither the White House nor federal law enforcement agencies have confirmed any disciplinary action taken against Monaco. Microsoft declined to comment on the former president’s statement.

Monaco joined Microsoft in July, according to her LinkedIn profile. She previously held senior roles in the Obama and Biden administrations, including Assistant Attorney General for National Security and Deputy Attorney General. Her appointment was highlighted earlier Friday by Fox Business anchor Maria Bartiromo, who referenced a University of Chicago Law School article noting her transition to the private sector.

The controversy has drawn renewed attention to Microsoft’s extensive contracts with the U.S. government. The tech giant provides cloud infrastructure, cybersecurity solutions, and productivity software to numerous federal agencies. Earlier this month, Microsoft announced it had helped federal clients save $3.1 billion through its digital services.

Trump’s post also follows a separate corporate decision by Microsoft to end certain AI and cloud services to a unit of the Israeli military. The move came after internal investigations into claims that the unit was using Microsoft’s tools to monitor Palestinian phone communications.

The timing of the controversy is notable. Trump is scheduled to meet with Israeli Prime Minister Benjamin Netanyahu on Monday, while Microsoft CEO Satya Nadella recently joined other tech leaders for a high-profile dinner at the White House focused on artificial intelligence and global tech governance.

Monaco has yet to publicly respond to Trump’s remarks.
