Gillian Turner said on "Outnumbered" that the attack on congressional Republicans' baseball practice is a "wake-up call" for Washington, D.C. to return to bipartisanship.
The shooting, reportedly by a man who supported Bernie Sanders, wounded House Majority Whip Steve Scalise, a congressional aide and two police officers.
"It's now incumbent upon the governing class in Washington to do their best to, if not end the gridlock, then at least end the hellacious, completely critical rhetoric that has just done nothing but divide our nation over the last election cycle," said Turner, a Fox News contributor and former White House National Security Council member under Presidents Bush and Obama.
She called on members of Congress and the executive branch to end the "heated" daily rhetoric.
"It puts a fine point on the problem at hand. It's a wake-up call for bipartisanship," she said.
Melissa Francis echoed the call for politicians to "turn the temperature down" in Washington.
Earlier on the show, former House Speaker Newt Gingrich said the shooting is part of a pattern of "an increasing intensity of hostility on the left."
He said that the violent feelings of people who disagree with conservatives have been building since election night.
Abby Huntsman and Gingrich said the president struck the right tone of unity in his message from the White House on the shooting.
