A former Illinois mayor pleaded guilty to corruption charges on Wednesday, a day after he resigned from office.

Louis Presta, the former mayor of Crestwood, Illinois, admitted to U.S. District Judge Thomas Durkin that he sought cash payments from a representative at SafeSpeed, a red-light camera company. He then pleaded guilty to a bribery and official misconduct count, as well as to filing a false income tax return. If charged, he could face a prison sentence of two years or more, according to the Chicago Sun-Times.
