More questions than answers now when it comes to the attack on Paul Pelosi, the husband of House Speaker Nancy Pelosi. Police say he was attacked by a man with a hammer after officers arrived to the scene early this morning and found both men holding that hammer.

Media reports say the suspect asked "Where's Nancy?" This raises questions about political extremism and violence.
