Ahumada deferred comment to his attorney, Star Jones, who declined to comment on the prosecutor's statement.
The driving-while-intoxicated charge is the third to be filed against the mayor since 1987. One led to a misdemeanor conviction while the other was dropped.
Despite the prosecutor's statement, Villalobos may lack the authority to remove Ahumada from office. According to The Herald, Brownsville's city charter requires a recall election to remove a member of the city commission. That would include the mayor.
