Homeland Security details "one of the most violent days" of Operation Midway Blitz amid President Donald trump's crackdown on illegal immigration.

While ICE and CBP are part of DHS and conduct immigration enforcement, officials under oath described methods and tactics that differ, the ABC7 I-Team has learned.

The Trump administration has sent ICE agents to cities across the nation to carry out Trump’s deportation goals. In September, DHS launched an immigration enforcement operation dubbed “Operation Midway Blitz” in Illinois after a 20-year-old woman, Katie Abraham, was killed in a drunk-driving, hit-and-run by an undocumented immigrant.

In a raid Sunday in southwest Idaho, U.S. Immigration and Customs Enforcement arrested 105 people. The Federal Bureau of Investigation previously announced five arrests of people linked to the alleged illegal horserace gambling operation in Wilder called La Catedral Arena.

Va., argues DHS violated the Antideficiency Act when it transferred staff to agencies focused on border security and deportation work.

Immigration judges are the only ones who can revoke someone's green card or issue a final order of removal for certain people.

Legal experts say it’s becoming increasingly unclear where lawful enforcement ends and potential overreach begins.
