Rep. Rodney Davis, R-Ill., who was at the Republican baseball practice when a gunman opened fire, held up a piece of shrapnel from the shooting as a reminder what can happen when political rhetoric becomes too heated.

"I was cleaning out my baseball bag the day after the shooting, after we played our congressional baseball game for charity, and as I pulled something out from the area where you store your bats, I saw something drop on the ground," Davis told "Fox News Sunday."

Davis then held up a piece of shrapnel "from a madman who came to politically kill innocent people."

"This is the reminder that all of us have that we have to take a step back in this country, we have to tone down this rhetoric and we've got to come together as a nation, as Americans, and say enough is enough," he continued.

Davis called for Americans on both sides to the aisle to stand up "to the hate on both sides" because it can lead to people being killed.

Four people were shot Wednesday when a gunman opened fire in Alexandria, Va. House Majority Whip Steve Scalise is still in the hospital recovering from his gunshot wounds.
