WASHINGTON (TNND) — White House border czar Tom Homan defended President Trump’s decision to dispatch the National Guard to Chicago. Homan said the move could begin as soon as next week in an interview with CNN.

Homan told Jake Tapper of State of the Union on Sunday, “You can expect action in most sanctuary cities across the country. President Trump’s prioritized sanctuary cities because sanctuary cities knowingly release illegal alien public safety threats to the streets every day. That’s where the problem is.”

President Trump dispatched the National Guard to Washington in August despite opposition from DC residents. Trump has since boasted that the city is “NOW A CRIME FREE ZONE,” and turned to cities such as Chicago, New Orleans and Baltimore to expand his crackdown on immigration and crime.

“We’re going in,” Trump said, describing a National Guard deployment to the capital of Illinois last Tuesday.

“They’re a force multiplier,” Homan told Tapper about the National Guard. “They’re on the table. I mean, they have been used by every administration since I have been working for the government starting in 1984. Every administration has used the Guard and the military on the border. And they have been very beneficial.”

Trump further escalated tensions on Saturday after a post on Truth Social depicting himself as Lt. Col. Bill Kilgore from “Apocalypse Now,” a 1979 film on the Vietnam War.

The post reads, “Chicago about to find out why it’s called the Department of War,” referencing the order he signed on Friday, renaming the Defense Department to the Department of War.
