Bill Cosby sues seven accusers for defamation

Bill Cosby is hitting back at the accusers who allege he sexually assaulted them.

The comedian is suing seven women: Tamara Green, Therese Serignese, Linda Traitz, Louisa Moritz, Barbara Bowman, Joan Tarshis and Angela Leslie. Cosby filed the lawsuit in a Massachusetts federal court.

Cosby's lawyer, Monique Pressley, released a statement on Twitter, calling the women's accusations "malicious, opportunistic, and false and defamatory." It also states that the women "knowingly published false statements and accusations."

Cosby is suing for defamation, tortious interference and intentional infliction of emotional distress, according to the statement.

The lawsuit comes after the seven accusers filed a federal lawsuit against Bill Cosby, claiming the comedian sexually abused them and later defamed them by calling their accounts lies.
