Admits extramarital affair. Three aides of his are fired or forced out after an investigation.

And he refuses to step down.

Ohio’s attorney general admitted an extramarital affair with an employee Friday, soon after three of his aides were fired or forced out after an investigation found evidence of sexual harassment and other misconduct.

Leader of both parties were critical of Attorney General Marc Dann, one of several Democrats swept into office in 2006 after a scandal over state investments sullied Republicans. He apologized to his wife and supporters but promised not to step down.

“I’m embarrassed. I have taken responsibility for what I’ve done,” he told reporters.

Dann had lived with two of the aides at an apartment during much of his first year in office and some of the alleged harassment by one of the aides occurred there.

“I did not create an atmosphere in my public and personal life that is consistent with the important mission of the Office of Attorney General …,” Dann said. “I am heartbroken by my failure to recognize the problems being created and by my failure to stop them.”

Ohio GOP deputy chairman Kevin DeWine called for Dann’s resignation, saying he turned the attorney general’s office into a “raunchy frat pad.”

Democratic Gov. Ted Strickland said the investigation showed a “double standard” with Dann staying while some employees were let go.
