'Those people will pay': Biden vows to take action against border patrol agents on horseback in Del Rio In his first extended comments on the treatment of Haitian migrants at the southern border, Biden said that, as president, he takes responsibility for what happened. Homeland Security Secretary Alejandro Mayorkas is already conducting an investigation that he has said will be completed by next week. The administration has also temporarily suspended horse patrols in Del Rio, Texas. “It’s dangerous. It’s wrong. It sends the wrong message around the world and sends the wrong message at home," Biden said. "It’s simple not who we are.” 📸: Evan Vucci (@apnews) | #biden #borderpatrol #delrioborder #haitianmigrants
