Intruder beats Pelosi's husband with hammer in their home

U.S. House Speaker Nancy Pelosi's husband was severely beaten with a hammer Friday morning when an attacker broke into their San Francisco home. The speaker was not there at the time. Authorities said the suspect specifically targeted the home and shouted "Where is Nancy?" before assaulting her husband. As Lisa Desjardins reports, the attack comes as threats to lawmakers are at an all-time high.
