Thomas Douglas Homan (born November 28, 1961) is an American political commentator and former government official who served as acting director of U.S. Immigration and Customs Enforcement (ICE) from January 2017 to June 2018. He has been a prominent figure in U.S. immigration enforcement, known for advocating the deportation of undocumented immigrants and opposing sanctuary city policies. Homan is considered one of the main proponents of the policy of separating children from their parents to deter illegal immigration, a policy adopted during the Trump administration. Homan began his career in law enforcement as a police officer before joining immigration enforcement in 1984. He served as a Border Patrol agent and held various supervisory roles throughout his career, including executive associate director for Enforcement and Removal Operations at ICE. In 2017, then-President Donald Trump appointed him acting director of ICE. After retiring from government, Homan worked as a political commentator for Fox News and in 2024 was designated by Trump as "border czar" for Trump's second presidency, a role focusing on immigration enforcement and border security. In 2024, Homan was recorded in an FBI undercover operation accepting $50,000 in cash, leading to a federal investigation that was closed in 2025 due to insufficient evidence of criminal wrongdoing. Despite this, he remains a key figure in immigration policy circles aligned with conservative and Trump-aligned positions.
