Homeland Security Secretary Alejandro Mayorkas vowed a swift investigation into the treatment of Haitian migrants on the Texas border by agents on horseback, telling a House panel that the inquiry would be completed within days.
Mayorkas told the House Homeland Security Committee that an undisclosed number of agents had been placed on administrative duty as investigators examine confrontations in which some mounted agents appeared to use their reins as whips against migrants who have been surging into Del Rio, Texas.
"I want to assure you that we are addressing this with tremendous speed and tremendous force," Mayorkas said. "The facts will drive the action we take."
Images of the mounted agents driving some migrants back across the Rio Grande River prompted national condemnation.
Mayorkas said the actions were "met with our nation's horror because they do no represent who we are as a country."
