Lawmakers are rethinking security after Arizona Rep. Gabrielle Giffords was shot in her home district on Saturday. Tensions are also high among staffers and employees who head to work on the Hill every day.
Edna Thomas exits the Capitol South Metro Station and hurries across the street towards her office at the Library of Congress. She says she's still reeling from hearing about the attack on Giffords.
"...every time something happens like that it's just going to heighten security up here...and even to the metro I was just looking today and wondering what's in that bag. And I've never had to think of stuff like that -- that you now just have to be afraid," Thomas says.
Giffords was shot while speaking to constituents in the parking lot of a Safeway grocery store in Tucson. In the wake of the attack, a few lawmakers with permits to carry concealed weapons say they'll be carrying guns more often when attending events in their home districts.
Meanwhile, the Capitol Police force is also reassessing security measures in Washington and around the country.
