Two U.S. attorneys and two journalists who have been working with members of a Central American caravan in Mexico have been removed from Mexico after their passports were “flagged.” It’s unknown where the orders to restrict their travel came from. Nora Phillips and Erika Pinheiro are attorneys with Al Otro Lado, an immigrant rights group that in 2017 filed a lawsuit accusing Customs and Border Protection of depriving asylum seekers access to the asylum process. In a tweet, the American Immigration Lawyers Association said it is urging Congress “to conduct a thorough and immediate investigation” into the removals.
