One of Cooley's 2008 re-election opponents, Albert Robles, faced misdemeanor charges filed against him by the D.A.'s office in November 2007. Robles was charged with printing a pair of political mailers without a return address and expending more than $100 cash in a political campaign. Robles accused Cooley of direct involvement in the charges brought against him because of a personal vendetta and to affect the outcome of the June 2008 D.A. election. Cooley denied those allegations. In October 2008, a jury found Robles not guilty of all charges after deliberating for only 20 minutes, and he was re-elected a month later to his seat on the board of the Water Replenishment District of Southern California.
