Report: Mounted Border Patrol agents being investigated over debunked narrative face suspension

The Border Patrol agents at the center of a controversy in which they were falsely accused of "whipping" Haitian migrants will likely only receive a light slap on the wrist pending the outcome of an investigation.

What is the background? 

Homeland Security Secretary Alejandro Mayorkas promised a swift investigation into the incident between Border Patrol agents on horseback and Haitian migrants.

"I want to assure you that we are addressing this with tremendous speed and tremendous force," Mayorkas told lawmakers last week. "It will be completed in days – not weeks."

Days later, President Joe Biden promised to make the agents involved in the incident "pay" for their actions.
