This morning's shootings in southern Arizona are having ripple effects here on Capitol Hill.
U.S. Capitol Police are warning all staffers and Members of Congress to take "reasonable and prudent precautions regarding their personal security," after Congresswoman Gabrielle Giffords was shot earlier today. That's according to an email sent out on Capitol Hill moments ago and reprinted at NationalJournal.com.
Capitol Police say the man suspected in the shooting has been arrested but they have no further details on his motive.
Giffords was meeting with constituents at a supermarket in her home district of Tucson, Arizona when a man reportedly shot her in the head at point-blank range. Twelve others were also injured in the attack.
