Bill Cosby's wife is speaking out about the comedian's sexual assault conviction.

Camille Cosby released a statement Thursday that called for a criminal investigation into the prosecutor in her husband's trial, blaming media "propaganda" for whipping up a "frenzy" that made the public unfairly biased against him, The Associated Press reports.

The former comedian was found guilty on three counts of indecent aggravated assault last month. His wife wrote that his conviction was the result of an "unethical" trial, and said that members of the district attorney's office in the Philadelphia suburb where Cosby was tried were "exploitive and corrupt," seeking to "advance themselves professionally and economically at the expense of Mr. Cosby's life." Camille Cosby also argued that the trial was tainted by public opinion, claiming that jurors were not objective because media outlets violated the First Amendment by failing to report the real truth. "This is mob justice, not real justice," she wrote.

Prosecutors denounced the statement. "Twelve honorable jurors — peers of Cosby — have spoken," one lawyer told AP. "There is nothing else that needs to be said."

Following his conviction, Cosby faces up to 30 years in prison. He is on house arrest awaiting sentencing. Summer Meza
