WASHINGTON (AP) — A U.S. official says the Biden administration is opening an investigation into labor and human rights abuses in Nicaragua. The move affects relations with a country the U.S. has a free trade deal with amid growing concerns over President Daniel Ortega’s increasingly authoritarian rule. The investigation being opened by the Office of the U.S. Trade Representative is expected to last a year. That’s according to the official and another person familiar with the probe who spoke to The Associated Press on the condition of anonymity to discuss the probe before it is announced.
