Political Violence Escalates: Man Attacks Rep. Connolly's Staff with Baseball Bat.

A man wielding a metal baseball bat entered the office of Democratic Rep. Gerry Connolly in northern Virginia on Monday and attacked two members of his staff. The suspect, identified as Xuan Kha Tran Pham, 49, of Fairfax, Va., was taken into custody by officers who had to use a taser to subdue him. Pham has a violent history and was accused of attacking police officers last year. His father told the Washington Post that his son is schizophrenic and had dealt with mental illness since his late teens.
