Around the Capitol, officers with large weapons were patrolling Monday, checking cars for explosives and making their presence known to any potential threats.
D.C. Delegate Eleanor Holmes Norton says she's jubilant at the news that al-Qaida's leader was taken out, but she says it's a reminder that security officials need to stay alert.
"Al-Qaida is interested in big bang. And they could go for where they think there are a lot of federal employees, where they think there are a lot of members of Congress or other federal officials," she says.
D.C. Mayor Vincent Gray met with his top security staff Monday and the District's director of Homeland Security. He says he's already upped the District's police presence too, and that they remain on high alert.
"We are the nation's capital, so we could be certainly more of a target than virtually any place else," he says.
No announcement has been made on how long heightened security will continue around the region.
