Some of the 8,000 migrants arrested under the Trump administration's deportation crackdown have already been released back into the U.S., according to a report.
Agents from Immigration and Customs Enforcement have conducted raids in cities such as New York, Chicago and Philadelphia, arresting immigrants who entered the U.S. illegally. The surge in arrests has come as Donald Trump returns to the White House and works to fulfill a campaign promise to deport millions of illegal migrants.
