The U.S. Border Patrol is proposing disciplinary action for several agents who confronted Haitian migrants while on horseback on the Texas-Mexico border last year. 

U.S. Customs and Border Protection Commissioner Chris Magnus, which oversees Border Patrol, would not reveal what the disciplinary action may be, citing privacy concerns for its agents. But he stressed that some of the actions by the agents on horseback and verbal epithets yelled by at least one agent led to the recommendations and were result of a 10-month investigation into the incident. 

The disciplinary process is ongoing and the agency’s Office of Professional Responsibility will finalize the recommendations, which the agents could later appeal, he said. 

“There is no room in our agency for discrimination or intolerance,” Magnus said at a press conference Friday. “CBP is dedicated to ensuring the fair and just treatment of all people.”

Images of Border Patrol agents on horseback in September repelling Haitian families as they waded across the Rio Grande into the United States circulated through newscasts and social media sites, sparking a sharp backlash against the agency. 

Immigrant rights and civil rights groups protested the clashes. In Miami, 200 Haitian-Americans protesting outside the U.S. Citizenship and Immigration Services field office forced road closures.

At the time, Homeland Security Secretary Alejandro Mayorkas ordered an investigation into the incident. Mayorkas in a statement Friday said CBP is implementing the needed reforms after the investigation that will “proceed with the urgency and commitment.” 

“The misconduct of several individuals does not reflect the brave and distinguished service of the agents of the United States Border Patrol,” Mayorkas said in the statement. “The organizational failures of policy, procedures and training that the investigation identified were a disservice to the agents and the public they serve. CBP must and will do better.”

CBP investigators interviewed more than 30 eye-witnesses, including news media members at the scene, as well as Border Patrol agents and officials to compile the 500-page report, Magnus said. 

“The primary goal of this investigation was to establish the facts of what happened,” he said. “It was thorough and independent. And despite any comments or criticisms – not everyone’s gonna like all the findings – but the investigation was comprehensive and fair.”
