Career

U.S. House of Representatives

Michael Guest represents Mississippi's 3rd congressional district in the U.S. House of Representatives as a Republican. In Congress, Guest has focused on several key policy areas, including homeland security, border enforcement, veterans' affairs, and law enforcement support.

Homeland Security and Border Security

Guest serves on the House Committee on Homeland Security, where he holds the chairmanship of the Subcommittee on Border Security and Enforcement. In this capacity, he has been a vocal advocate for strengthened border security measures and immigration enforcement. In July 2025, Guest authored an opinion piece published in Newsweek in which he discussed the passage of what Republicans termed the "One Big Beautiful Bill," legislation that included provisions aimed at securing the nation's borders. In the piece, Guest outlined what he believed were necessary next steps for border security policy following the bill's passage.

In December 2025, Guest appeared on Newsmax and NewsNation alongside House Committee on Homeland Security Chairman Andrew R. Garbarino of New York ahead of a hearing focused on rising threats to law enforcement. The hearing examined challenges facing law enforcement officers across the country, a topic closely aligned with Guest's background as a former prosecutor.

Veterans' Affairs

Guest has been active in legislative efforts related to honoring and supporting military veterans. In November 2025, ahead of Veterans Day, Guest introduced a resolution in the House of Representatives aimed at honoring the service of military veterans. The resolution was timed to coincide with the Veterans Day observance that week.

Financial Disclosures and Stock Transactions

As a member of Congress, Guest is subject to the provisions of the Stop Trading on Congressional Knowledge Act (STOCK Act), which requires members to disclose securities transactions within a specified timeframe.

Guest also sold shares of Dynatrace, a software intelligence company, with the transaction disclosed in a filing reported in February 2026.
