Acting Director of U.S. Immigration and Customs Enforcement Thomas Homan said his agency is going to increase workplace immigration enforcement.

In a speech to the conservative Heritage Foundation in Washington on Tuesday, Homan such enforcement will increase four to five times current levels.

"[A]s long as they think they can come here and get U.S. citizenship and not get removed, they're going to keep coming," he said during a Q&A session. "As long as they can come here and get a job, they're going to try and come."

Homan said ICE has already stepped up workplace enforcement since the Trump administration took office, and revealed he has given instruction to increase it "four to five times."

"We're taking worksite enforcement very hard this year. We've already increased the number of inspections and worksite operations, you're going to see that significantly increase this next fiscal year," he said.

Homan explained ICE is also going to strongly prosecute employers who knowingly hire illegal immigrant workers, in addition to deporting those workers.

The remarks came after a 30-minute-plus tirade against so-called sanctuary jurisdictions, which both President Trump and Attorney General Jeff Sessions have already pledged to end.

Homan said ICE will continue to strongly target illegal immigrants who are part of gangs. But, if someone is still undocumented even without provable gang ties, they will still be deported, he said.

"Will we continue to arrest people at courthouses? Absolutely [we] will," Homan said, adding that "sanctuary cities are releasing public safety threats back into the public. That doesn't make sense to me."

ICE will continue to arrest illegal immigrants at other various places that draw criticism, including near schools.

Churches and hospitals are not part of those enforcement sites, Homan said.

Homan also bashed press critical of the Trump administration's immigration actions in what they describe as "raids" or "sweeps," "shame on these folks," he said.

"We conduct targeted enforcement operations," Homan explained.
