President-elect Donald Trump’s incoming border czar Tom Homan has issued a stern warning to migrants illegally entering the U.S. in the final days of the Biden administration.

Homan has been a vocal proponent of Trump’s mass deportation plan that would target illegal migrants throughout the U.S. Last month, he met with New York City Mayor Eric Adams to discuss cooperating to resolve issues related to the sanctuary city’s migrant crisis.

In a Sunday appearance on Fox News, Homan warned recent arrivals to the U.S. under President Joe Biden to prepare for a hasty departure under the incoming Trump administration.

“We are trying, but this administration, even after what happened the last couple of days, they’re still bringing thousands through the CBP One app, the CHNV program from Cuba, Nicaragua, Haiti, Venezuela,” Homan said. “They’re going to do as much damage as they can until President Trump walks back to that office.”

But a message to those thousands that they’re still bringing in every day,” he added. “You’re going home.”

Homan also touched on plans to add to the southern border wall between the U.S. and Mexico. He credited the wall with helping curb illegal immigration and influxes of illegal drugs, noting “walls work.”

“Walls save lives,” he said. “Women and children cannot go without walls.”

The incoming Trump administration, he added, will conduct the “biggest border operation this country has ever seen.”

The message follows Homan saying last week the incoming administration needs to address “insider” threats, referencing the recent New Orleans terror attack and explosion of a Cybertruck in Las Vegas. Authorities have said former members of the military carried out both incidents.

“We need to drill down and find out about this inspiration and what insider threat is currently in the United States government, military and in the United States government service and address them right away,” Homan said. “We gotta address insider threat. We have to. We can’t let this go on any further.”
