Some people caught in Trump administration immigration operations have already been released back into the United States on a monitoring program.

Specifics of detainments have been scarce, leaving it unclear whether the criminals being targeted make up a significant share of those being captured.

Texas National Guard soldiers now have the authority to make immigration arrests and help detain and deport undocumented people under an agreement between the state and the Trump administration that requires those duties be done under the supervision and direction of a U.S. Customs and Border Protection official.
