President Donald Trump has raised fresh concerns about national security after calling on Microsoft to dismiss Lisa Monaco, their newly appointed President of Global Affairs.

On September 26, 2025, Trump posted on Truth Social demanding her removal, citing her past role in investigations against him during her time as Deputy Attorney General in the Biden administration.

Trump’s criticism focuses on Monaco’s involvement in high-profile cases including the January 6 probe and the Mar-a-Lago investigation. With Microsoft managing key government contracts, Trump suggested her appointment could pose risks, describing her as “corrupt” and “a danger to U.S. national security.”

How The Controversy Started

The issue gained traction after journalist Laura Loomer flagged Monaco’s hiring in July 2025. Loomer called the move “treason,” pointing to Microsoft’s defense ties.

Trump quickly responded, echoing her warnings and urging immediate action. His post sparked strong online reactions, generating over 500,000 impressions and driving hashtags such as #FireLisaMonaco and #TrumpDeepState.

Supporters argue that Monaco’s history makes her unfit to oversee sensitive matters tied to government operations. Trump’s team had already revoked her federal clearances earlier this year, citing alleged misconduct. Critics now question whether her role at Microsoft could influence how the company handles its cybersecurity and government relations.

Differing Reactions

The response has been divided. Right-leaning voices see Trump’s call as necessary to protect national interests. Posts on X describe Monaco’s appointment as “infiltration, not business,” warning that her position could weaken trust in Microsoft’s government contracts.

On the other hand, mainstream outlets like Reuters and Politico frame Trump’s remarks as political retaliation. Supporters of Monaco emphasize her legal background and argue that the criticism is part of Trump’s broader conflict with former officials from the Biden administration.

Why It Matters

The debate highlights three major concerns:

• National Security: With Microsoft deeply connected to U.S. defense projects, Monaco’s past role in investigations against Trump has raised suspicion among his supporters.
• Big Tech Oversight: Trump’s remarks underline growing calls to hold technology companies accountable for their hiring choices.
• Political Influence: The controversy adds to Trump’s larger campaign to challenge individuals he believes targeted him and his movement.

The Road Ahead

Microsoft has not commented on the criticism. CEO Satya Nadella has been tagged repeatedly on X, with some users calling for boycotts if the company does not respond. Trump allies point to past corporate shake-ups as proof that public pressure can lead to action.

For now, the question remains whether Microsoft will reconsider Monaco’s role or stand by its decision. The outcome could shape how Big Tech navigates political influence and national security concerns in the future.
