Rep. Mark Green, chairman of the House Homeland Security Committee, is stepping down from Congress in 2025 to launch a new private sector business venture.
Rep. Mark Green Steps Down from Congress to Launch New Business Venture
Rep. Mark Green, a Republican from Tennessee and the current Chairman of the House Homeland Security Committee, has officially announced his decision to step down from Congress to pursue opportunities in the private sector. In a video posted on X (formerly Twitter) on Friday, Green shared that he is starting a new business, signaling a major transition in his career after years of public service.
📢 Announcement Comes After Years in Public Office
Green had initially made his intentions clear in June 2025, when he first announced he would not seek re-election. However, Friday’s video message offered more personal insight into his decision and what lies ahead. “It’s time for a new chapter,” Green said, “and I’m excited to begin building something from the ground up in the private sector.”
The announcement came as a surprise to some within the GOP, especially given Green’s influential role in shaping national homeland security policy and border control legislation during his time in Congress.
🏛️ Green’s Legacy in Congress
Rep. Mark Green has been a U.S. Representative for Tennessee’s 7th Congressional District since 2019. A U.S. Army veteran and former state senator, Green brought a military background and conservative values to Capitol Hill. He quickly rose through the ranks to chair the House Homeland Security Committee, where he played a central role in efforts to enhance border security, cyber defense, and national emergency preparedness.
Under his leadership, the committee launched investigations into threats posed by foreign adversaries, including China, as well as critical infrastructure vulnerabilities. His tenure has been marked by vocal support for increased border enforcement, opposition to illegal immigration, and strong criticism of the Biden administration’s security policies.
💼 New Career in the Private Sector
In his announcement video, Green did not reveal specific details about the nature of his new business but emphasized that it is “an entrepreneurial venture that aligns with my values and experience.” Given his background in medicine, military service, and government, analysts speculate the new business could fall within healthcare, defense technology, or security consulting sectors.
Green previously founded and ran a successful emergency medicine group, giving him both business acumen and real-world experience in managing complex operations — traits that may prove beneficial in his new endeavor.
🔄 Political Repercussions and Next Steps
Green’s departure leaves a significant vacancy in the Republican leadership, particularly in the Homeland Security Committee, which is currently navigating complex issues such as border security, cyber threats, and counterterrorism. His exit will also trigger a scramble to find a suitable replacement to carry forward the committee’s legislative agenda.
In Tennessee, Green’s departure opens the door for new Republican candidates to vie for the 7th District seat. While the district is considered solidly red, the primary is expected to be competitive given Green’s popularity and legacy.
🇺🇸 A Career of Service Continues
Though stepping away from public office, Green emphasized in his message that his “commitment to serving the country remains unchanged.” He expressed gratitude to his constituents, colleagues, and staff, stating, “It has been the honor of my life to serve in Congress.”
Political insiders suggest that this may not be the last we hear from Green. Some believe he may return to public life in the future — perhaps even in a gubernatorial or federal executive role — after building success in the private sector.
