U.S. Immigrations and Customs Enforcement Director Thomas Homan

Immigrations and Customs Enforcement Director Thomas Homan told lawmakers at a hearing on Capitol Hill on Tuesday that undocumented immigrants should be “uncomfortable” as he talked about needing more money for the next fiscal year to expand immigrant detention.

“If you’re in this country illegally, and you committed a crime by entering this country, you should be uncomfortable,” Homan said during a Tuesday House Appropriations Committee meeting on “Immigration & Customs Enforcement and Customs & Border Protection Budget.” “You should look over your shoulder.”

Federal immigration arrests have already been on a sharp rise since President Trump took office early this year. They could rise even more dramatically next year if Congress approves the administration’s multibillion-dollar budget proposal, the nation’s top enforcement official said Tuesday. The Trump administration will continue arresting undocumented immigrants who haven’t been convicted of crimes and won’t apologize for it, the acting director of Immigration and Customs Enforcement said.

ICE requested a $1.2 billion increase in funding for next fiscal year. Nearly $4.9 billion would expand immigrant detention to more than 51,000 beds from about 34,000 beds ― the number Congress requires ICE to maintain. With the new budget, ICE would also be able to hire an additional 1,000 enforcement officers and about 600 support staff to increase the rate of removing people.

House Democrats questioned the Trump administration’s plans to spend millions of dollars to lock up students and others who are in the country illegally but have not committed any crimes, according to the Washington Post, including Diego Ismael Puma Macancela a 19-year-old New York high school student who was detained last week hours before his senior prom. Macancela spent the day of his prom cowering in a bedroom closet hiding from immigration officers as they pounded on doors outside.

Macancela expected the authorities would be looking for him, the Post said, because a day before, ICE had arrested and detained his mother, an undocumented Ecuadoran immigrant who entered the United States illegally with him two years ago.

Homan said Macancela was subject to a final removal order, and was thus eligible for deportation. If people are in the U.S. and have a deportation order, they shouldn’t feel comfortable that they don’t have to worry about being arrested, he said.
