BROWNSVILLE, Texas (AP) — A city official in southern Texas has apologized for using a racial slur to describe two black assistant district attorneys.

The Brownsville Herald reports that multiple social media users posted audio clips this week featuring Brownsville City Commissioner Cesar De Leon. The clips recorded him using slurs and derogatory language when referring to two district attorneys working for the Cameron County District Attorney's Office.

De Leon says he's "very apologetic" for the profane language. He says the conversation was private and believes the discussion was recorded, edited and released by the person to whom he was speaking.

District Attorney Luis Saenz says he hires the most competent prosecutors without regard to their race. He says De Leon's comments "are very shameful and hurtful."
