Washington (CNN) The chairmen of the Democratic and Republican congressional campaign committees called on Americans from opposite sides of the aisle to "come together" in the wake of a mass shooting and bomb threats last week.

Ohio Rep. Steve Stivers, the National Republican Congressional Committee chair, and New Mexico Rep. Ben Ray Lujan, the Democratic Congressional Campaign Committee chair, said in a joint interview on NBC's "Meet the Press" that political rhetoric across the country needs to be kept civil.

"We all bear some responsibility, and we need to try to clean up our act and try to bring more civility to our Congress, and frankly, to our dialogue," Stivers said.

"It's not too much to expect leaders to bring us together, to unite our country, to find a way to reach out to us, to our greater good, and make sure that we rise above all of the accusations, the hate and finger-pointing," said Lujan.

Both agreed that they can work together in Congress on such things as lowering prescription drug costs and funding infrastructure development.
