Rep. Luis Gutierrez (D-IL) was handcuffed at an Immigration and Customs Enforcement (ICE) office in Chicago on Monday after staging a sit-in.

Gutierrez and a small group of advocates had attended an ICE meeting seeking information about specific immigration cases.

After not receiving the answers they sought, Gutierrez refused to leave.

One of the things the congressman was protesting was a series of tweets issued by ICE last week warning that those covered under the Deferred Action for Childhood Arrivals program weren't necessarily safe from deportation.

"Look, there's a lie, and the lie keeps repeating," Gutierrez told CNN. [The lie is that] "they're going after criminals, they're going after the bad people in the immigrant community."

"The fact is, they're going after DREAMers," he said. "Somebody has to stand up for them ... they are under threat."

"When you see unfairness and [injustice] ... it's part of what being an American is, is to stand up."
