The Department of Homeland Security is preparing to discipline "multiple" horseback Border Patrol agents involved in the infamous "whipping" incident of Haitian migrants at the U.S.-Mexico border back in September. 

A federal source told Fox News an announcement on the matter is expected within the coming days.

The source said that DHS will be putting forth proposals to discipline the agents who will have a chance to respond to the charges. The charges, Fox News is told, are "administrative violations," and do not amount to criminal conduct – of which the agents were previously cleared. 

Images emerged in September of Border Agents in Del Rio, Texas showing them on horseback, blocking migrants from entering the U.S. and, in one case, grabbing onto a migrant's shirt.

Many Democrats and media outlets falsely described the agents' long reins, which they use to control their horses, as "whips." 

ABC, CBS and NBC pushed the debunked claim that Border Patrol agents were whipping Haitian migrants, but didn't bother to inform viewers that it was discredited.

President Biden weighed in on the controversy, saying, "those people will pay." 

"There will be an investigation underway now and there will be consequences," Biden said at the time. "There will be consequences."

The agents involved were taken off their normal duties and have not been allowed to have contact with migrants since.
