The White House has said images of U.S. border patrol agents on horseback chasing Haitian migrants are "horrific." On Sunday, Haitian migrants trying to cross from Mexico into Del Rio, Texas, were chased by U.S. Customs and Border Patrol agents. Press secretary Jen Psaki said that while she needs more information on the situation, "they should never be able to do that again." "Of course they should never be able to do it again, I don't know what the circumstances would be, it's obviously horrific, the footage, I don't have any more information on it so let me venture to do that and we'll see if there's more to convey," Psaki said. 📸: Omar Ornelas, El Paso Times via USA TODAY Network and Paul Ratje, AFP via Getty Images.
