Judge Michael E. Farbiarz warned in an order on Monday that he may have to hold the Immigration and Customs Enforcement agency in criminal contempt.

A federal judge said U. S. attorneys working on immigration cases lack resources "and, in some cases, training" to comply with court orders.

In some two dozen cases stemming from President Donald Trump's immigration crackdown in Minnesota that CNN has reviewed, federal judges appointed to the bench by Democrats and Republicans have had to use terms like "contempt" and "noncompliance" to get the government's attention to respond to court orders.
