Haitian migrants wade across the Rio Grande from Del Rio, Texas, to return to Ciudad Acuña, Mexico, Sunday, Sept. 19, 2021, to avoid deportation to Haiti from the U.S. The U.S. is flying Haitians camped in a Texas border town back to their homeland and blocking others from crossing the border from Mexico in a massive show of force that signals the beginning of what could be one of America's swiftest, large-scale expulsions of migrants or refugees in decades.
