Piers Morgan, who was called out twice during the Murdoch hearings by MP Louise Mensch is not taking her “smear” lying down.

Mensch was on “The Situation Room” yesterday, and Morgan phoned in. Mensch says Parliamentary protections would keep her from repeating what she’d said about Morgan during the hearing.

Morgan wasn’t having it: “I call on you Ms. Mensch now to repeat it, show some balls, repeat what you said about me and then maybe go buy a copy of my book.”

Morgan then discussed the matter on his show, later.
