Lawmaker sees 'chilling effect' from shootings

WASHINGTON – The second-ranking House Democrat says the attack on an Arizona congresswoman can't help but have a chilling effect on lawmakers.

Rep. Steny Hoyer of Maryland says his colleagues in Congress have been very concerned about confrontations and growing anger they've seen in the political environment in the past few years.

Hoyer tells CBS' "Face the Nation" that many information outlets today are inciting people to anger. He warns those in politics, the media and the public square that their words can have consequences, and he urges people with differences to be civil.

In Tucson, Ariz., on Saturday, Democratic Rep. Gabrielle Giffords was critically wounded while meeting with constituents.
