President Trump ordered ICE to Sky Harbor Airport after negotiations failed to end a federal partial shutdown that stopped pay for TSA employees.

In a press release Monday, the Phoenix Sky Harbor International Airport said the city’s aviation department was notified that ICE agents will help TSA process passengers at security checkpoints.

Delta Airlines will launch flights from the Austin airport to Phoenix and Bozeman later this year along with new routes to several other cities in the United States.

Federal immigration officers have arrived at U.S. airports, fulfilling President Donald Trump's pledge to deploy them to help the Transportation Security Administration during a partial government shutdown.
