"There were people lying on the ground screaming, but he was targeting us", Loudermilk said. The congressman knelt down and prayed with him as paramedics flood the area, scrambling to treat six different people - including the shooter - who had been injured.
Its timing, coming after Wednesday's shooting, made it all the more disturbing.
The incident rattled Hill staffers as lawmakers, some still wearing team jerseys and holding their cleats, returned to their offices.
In May, two people were removed from a town hall meeting focused on health care held by GOP Rep. Kevin Cramer in North Dakota. He took cover in a dugout.
"They don't know me, they don't know my grandkids, they don't know the type of person I am, but he was targeting something that had been built in his mind, that he had created to be evil", he said.
Loudermilk also said that he carries a gun in Georgia, and when asked directly whether he thought House members should be able to carry, he replied "we need to look at security details".
"In hindsight, it was a little odd", he told CBC News, still in shock. Bernie Sanders, I-Vt., said on the Senate floor that the shooter apparently was a volunteer for his presidential campaign past year. His social media accounts were filled with anti-government rants.
"If it hadn't have been for those two officers", Loudermilk said, "it would have been a carnage".
"I suggest you prepare for the battle, motherf-- and the apocalypse", Howard said. "Thank God for the heroic service of the U.S. Capitol Police who prevented this awful shooting from being much worse", Scott said.
"When tragedy broke out today, two Capitol Police officers engaged and took down the shooter".More news: Wounded Pakistan look to overcome India for final glory

Loudermilk, who recalled seeing bark flying off an oak tree behind him when the shots began, pointed to the hostile tone of town hall meetings as a potential safety concern.
"President Donald Trump visited Scalise in the hospital, afterward tweeting in part: "... "But even if they are political, we all need to understand that we sometimes need to lower the rhetoric in political circles, and in the media, that does not raise the fears and the apprehensions of people that would lead them to do things like this".
Chaffetz wants USA marshals to be charged with assessing threats against members of Congress and securing them in more high-profile and widely attended events. "It's Time to Destroy Trump & Co".
Illinois Rep. Rodney Davis, who was up at bat when the gunfire started, told CNN on Wednesday the ratcheting up of incendiary partisan talk on both sides must stop.
"If we hadn't had those policemen out there, it would have been a massacre", he said. "I've been yelled at and spat on walking the streets of IL".
"I feel very safe and secure at the Capitol", Chaffetz said Wednesday. The event has already raised more than $600,000.
There was a lot of talk in the immediate aftermath of the shooting about political polarization, specifically the vitriol aimed at politicians.
The last time a shooting targeted a member of congress was the attempted assassination of Arizona's Rep.
Federal Bureau of Investigation agents arrested a man in the same Arizona district Gabrielle Giffords was shot in 2011 for making threats to shoot current Republican Rep. Martha McSally. "I just kept getting angrier and angrier", he said.
"When he got shot, he was down, stayed for the entire firefight". But maybe we'll learn from this one.
