Former Arizona Congresswoman Gabrielle Giffords says her heart is with her former colleagues, their families and staff and the Capitol Police following a shooting at a congressional baseball practice outside Washington.
She also says in a Twitter post that Capitol Police are "public servants and heroes today and every day."
Giffords was shot in the head at a meet-and-greet event outside a grocery store in Tucson, Arizona, in 2011.
Arizona Sen. Jeff Flake was among those participating in the baseball practice in Alexandria, Virginia, but not wounded.
Flake, a fellow-representative and friend of Giffords when she was shot, raced from metro Phoenix to the Tucson hospital where she was in surgery.
