VIDEO : Federal Judge Ruled Camille Cosby Will Be Forced to Testify

Bill Cosby's wife will be forced to testify in a defamation lawsuit filed by seven women who accuse the comedian of sexually assaulting them decades ago.

A federal judge on Thursday denied a motion by Camille Cosby to throw out a subpoena requiring her to give a deposition in the lawsuit. She is scheduled to be deposed by lawyers for the women on Wednesday.

U.S. Judge Magistrate David Hennessey in Springfield, Massachusetts, said Camille Cosby failed to prove that she and her husband were protected by the state's marital disqualification law. He also rejected claims that the value of the testimony would be outweighed by the "undue burden" the deposition would cause.
