Second Trump administration (2025–present)
President-elect Trump announced on November 10, 2024, that Homan would join the incoming administration as the "border czar", writing, "Homan will be in charge of all deportation of illegal aliens back to their country of origin." Trump planned to use the Alien Enemies Act of 1798 in efforts to deport illegal immigrants.
In February 2025, Hatewatch reported that Homan met multiple times with Proud Boys associate Terry Newsome. Two encounters occurred after the 2024 United States presidential election, presumably to discuss mass deportation. The Southern Poverty Law Center noted that "Homan was also a guest on Newsome's podcast in October 2024 and was a featured speaker at an anti-immigration event Newsome hosted in Chicago in June 2024."
Also in February 2025, while appearing with New York City mayor Eric Adams on the Fox News program Fox & Friends to discuss Adams's cooperation with ICE on immigration issues, Homan said, "If he doesn't come through, I'll be back in New York City, and we won't be sitting on the couch—I'll be in his office, up his butt, saying, 'Where the hell is the agreement we came to?'"
The same month, Homan got into a dispute with U.S. Representative Alexandria Ocasio-Cortez over educating immigrants about their constitutional rights, which he said "impedes" law enforcement. He said that he had asked the Department of Justice to investigate whether Ocasio-Cortez's actions impede ICE and whether she could be prosecuted, telling Fox News host Laura Ingraham, "maybe AOC's gonna be in trouble now." Ocasio-Cortez responded on social media: "'MaYbe shE's goiNg to be in TroUble nOw.' Maybe he can learn to read. The Constitution would be a good place to start."
In March 2025, two planeloads of people the Trump administration alleged were Venezuelan gang members were deported to El Salvador, defying a court order blocking the deportations. Homan told the media that the administration completed the deportations despite the court order because the court order was made when the planes were above international waters after leaving the U.S. He also said of deportations: "Another flight every day. [...] We are not stopping. I don't care what the judges think."
On April 17, 2025, Homan was interviewed by Kaitlan Collins about the deportation of American citizens to foreign prisons. He said that was "out of his lane" and threw the question over to Attorney General Pam Bondi.
The Trump administration said that around 140,000 people had been deported as of April 2025, though some estimates put the number at roughly half that amount.
On May 27, The Washington Post reported that Homan has disclosed consulting fees from the private prison firm GEO Group, one of the two publicly traded companies that profit from Trump's immigration policies.
Homan has been critical of people actively using their constitutional and legal rights and sharing knowledge of those rights, calling it "defiance", and has said that people knowing their rights impaired law enforcement activities.
In a June 2025 interview, Homan said that deportations should prioritize those who had committed crimes in the US.
