The Texas National Guard is leaving Illinois after being activated and sent, but never deployed.

A National Guard defense official from the U.S. Northern Command confirmed Sunday that all 200 Texas National Guard members now in Illinois will be leaving in the coming days. It was not clear whether the Texas troops were homebound or headed elsewhere.

The Illinois National Guard remains activated at this time, but the Texas National Guard is returning to Texas, the official said.

The Texas National Guard members arrived in Illinois in early October. They were stationed at the U.S. Army Reserve Training Center in Elwood, near Joliet, about 50 miles southwest of Chicago. 

The National Guard troops from Texas were originally brought in to protect federal immigration agents and facilities. But a federal judge blocked a National Guard deployment to the Chicago area pending a decision from the U.S. Supreme Court, and so the Texas troops were never deployed.

It was not clear what would happen next with the Elwood training center now that the National Guard members are leaving. CBS Skywatch was over the training center on Monday, where most of the doors to the barracks were wide open with no signs of anyone in fatigues.

Meanwhile, U.S. Customs and Border Patrol Cmdr. Gregory Bovino has left Chicago for North Carolina. The man who has led the Chicago immigration crackdown, "Operation Midway Blitz," left the city Thursday, CBS News confirmed the following day.

Bovino posted a montage to his X account Sunday afternoon, splicing together videos of U.S. Customs and Border Patrol making arrests in the Chicago area. In at least one instance, federal agents smashed the car window of an American citizen who was born in Honduras because he would not open his door.

The man was injured.

Immigration advocates from the Chicago area said they are sharing tips with people out east.

"We're talking to our brothers and sisters over in North Carolina, in Charlotte, and letting them know the tactics that we used, the methods that we used, what worked, what didn't work," said Baltazar Enriquez, president of the Little Village Community Council.

Border Patrol is eyeing New Orleans next. That city has been in the midst of an immigration crackdown for a few months.

U.S. Immigration and Customs Enforcement counts more than 20,000 deportations in the New Orleans area just in September and October.

Meanwhile, the U.S. Department of Homeland Security also closed its command center at Naval Station Great Lakes in the northern suburbs.

While Bovino has now left Chicago, Operation Midway Blitz is not over, according to sources. Some CBP agents are expected to stay in Chicago and the surrounding area.
