Former state Senator Martin Sandoval is scheduled to be arraigned today in federal court. The longtime Chicago Democrat was charged yesterday with bribery and tax offenses several months after federal agents raided his home and offices. The charges accuse him of taking bribes in support of the red-light camera industry while he served as the head of the Senate Transportation Committee. Sandoval is also accused of filing a false federal income tax return for 2017. He stepped down from his office earlier this month after announcing his resignation in November.
