Trump claims Lisa Monaco is a “national security threat” due to her past roles in former US President Joe Biden and former President Barak Obama’s Democratic administrations.
US President Donald Trump has called on Microsoft to dismiss Lisa Monaco, the company’s President of Global Affairs, alleging she poses a threat to national security because of her previous roles in Democratic administrations.
The demand, issued on Trump’s Truth Social platform on September 27, is the latest in a series of attacks targeting officials who were involved in investigations into his conduct while in office.
Monaco, a veteran of two administrations, served as Deputy Attorney General under President Joe Biden and as a national security adviser in the Obama White House. She joined Microsoft in July 2025, where she oversees cybersecurity policy and manages the company’s relations with governments worldwide.
US President described Monaco as a “menace to U.S. National Security,” arguing her access to sensitive data was “unacceptable” given Microsoft’s extensive federal contracts. He claimed Monaco had been stripped of security clearances, barred from federal facilities, and denied access to intelligence due to what he called “wrongful acts.”

Monaco was a central figure in the Justice Department’s investigations into Trump, including probes into alleged election interference and mishandling of classified documents. Those investigations were overseen by Attorney General Merrick Garland and led to multiple legal battles for the former president.
Microsoft declined to comment on President’s remarks. The company has longstanding partnerships with U.S. government agencies, including a recent $3.1 billion agreement to deliver cloud service savings across federal departments.
The controversy gained further traction after far-right activist Laura Loomer, a vocal Trump ally, claimed she had informed the President of Monaco’s hiring. Loomer has been a persistent critic of Microsoft and CEO Satya Nadella, repeatedly calling for an end to the company’s government contracts.
The President’s public pressure campaign echoes a similar episode earlier this year, when he demanded the resignation of Intel’s President Lip-Bu Tan before later praising the company after it struck an equity deal with Washington.
The move underscores Trump’s ongoing efforts to influence corporate America and to punish figures he views as political adversaries, signaling how the US President continues to blend politics, business, and personal grievances since his return to power.
