The Trump administration has issued a sweeping new order that could lead to the arrest of tens of thousands of refugees who are lawfully in the United States but do not yet have permanent residency. A memo filed by the Department of Homeland Security ahead of a Thursday federal court hearing in Minnesota says refugees applying for green cards must return to federal custody one year after they were admitted to the U.S. for reviews of their applications. DHS "may maintain custody for the duration of the inspection and examination process," said the memo, which was filed Wednesday.

Federal prosecutors have served six grand jury subpoenas to Minnesota officials as part of an investigation into whether they obstructed or impeded federal law enforcement during a sweeping immigration operation in Minneapolis-St. Paul area. A person familiar with the matter said Tuesday that the subpoenas, which seek records, were sent to the offices of Gov. Tim Walz, Attorney General Keith Ellison, Minneapolis Mayor Jacob Frey, St. Paul Mayor Kaohly Her and officials in Ramsey and Hennepin counties. The person was not authorized to publicly discuss an ongoing investigation and spoke to The Associated Press on condition of anonymity. Walz and Frey have called the probe a bullying tactic meant to quell political opposition.
