An appeals court has suspended a decision that restricts the aggressive tactics of immigration officers in Minnesota. The government persuaded the appeals court to freeze a judge’s ruling that bars officers from using tear gas and taking other steps against peaceful protesters in Minnesota’s Twin Cities. The stay is in effect while the government appeals. Meanwhile, an official in Maine turned down a request for more undercover license plates for U.S. Customs and Border Protection vehicles. The Maine secretary of state cited “abuses of power” during the Trump administration’s immigration crackdown.
