The former chairman of the Montgomery County Republican Party, accused of drugging and raping a woman, will be facing a trial.

Robert Kerns waived his right to a formal arraignment. He's accused of raping a female employee at his former law firm after a party in Franconia Township in October.

Authorities said Kerns secretly drugged the woman with Ambien and then raped her while she was unconscious.

Kerns since resigned his position as party leader.
