Cosby wants taped calls with accuser's mom banned from trial

Bill Cosby's lawyers want a judge to suppress taped phones calls he had with his accuser's mother. This comes as the defense starts trying to chip away at the trial evidence.

The actor and comedian is accused of sexually assaulting Andrea Constand in 2004.

She told her mother a year later, prompting Gianna Constand to call Cosby from their Ontario, Canada, home and give the recordings to police.

Cosby on tape describes a sexual encounter with her daughter and fears sounding like a "dirty old man with a young girl."

Cosby's lawyers in motions Wednesday say the phone calls violate Pennsylvania wiretap laws that require two-party consent.

However, lawyers for the Constands have said they followed the law in Canada where the recordings were made.

No trial date has been set.
