One injured aide has been released. And last November, Hillary Clinton beat Trump by just a few thousand votes. Duncan and Brooks were at the Alexandria, Virginia, field where GOP members of Congress were practicing for a congressional baseball game Wednesday, although Duncan left before the shooting began.
The officers were on hand due to the presence of Louisiana Rep. Steve Scalise, a senior House member and Republican leader who was wounded in the attack.
Saclise's doctor, Jack Sava, said Scalise will need further operations but he is expected to be able to walk and run again.
"His condition is critical, and he will require additional operations", the hospital said.
Lobbyist Matt Mika was struck multiple times in the chest is in serious condition at George Washington University Hospital.
A spokeswoman for Capitol Police did not return CNN's request for comment.
Rep. Trent Franks told Kate Bolduan on "Erin Burnett OutFront" that he has also been contacted by Capitol Police.
Former Alexandria Mayor Bill Euille, a YMCA regular, said he spoke to Hodgkinson numerous times and even offered him job advice. Sanders acknowledged Wednesday that Hodgkinson had apparently been among many volunteers on his 2016 campaign.
Sue Hodgkinson talked with reporters briefly in Belleville, Illinois, on Thursday - in part to ask the media to stop disrupting the neighborhood. Federal Bureau of Investigation agent Tim Slater said the Federal Bureau of Investigation needs the public's help in piecing together Hodgkinson's whereabouts and activities while he was in Alexandria.
Hodgkinson was a volunteer for the Bernie Sanders presidential campaign previous year and has comments on his social media accounts strongly criticizing President Trump.
Fox News reported that it had confirmed the existence of a list found in Hodgkinson's possession, containing names of Republicans.
Franks was not on the team, adding uncertainty about the significance of the list of names. As I walk across the parking lot to the vehicle, a gentleman approaches me and says, 'Can you tell me, the team today, is that Democrats or Republicans?' I told him it was the Republicans and he said, 'OK, thanks, ' and turned around.
Those who crossed his path, in the weeks before the shooting remembers Hodgkinson as an angry man, who took his anti-Republican rants online before going after the GOP during baseball practice.
