President Obama will be in New York City Thursday, to visit the site of the Sept. 11, 2001, terrorist attacks, according to an administration official.

Obama will also meet with the victims' families.

The president announced Sunday night that almost a decade after the terrorist attacks that killed nearly 3,000 people, a small team of U.S. forces killed 9/11 mastermind Osama bin Laden, who was holed up not in a cave but in a mansion in an affluent part of Abbottabad, a city about 30 miles north of Islamabad, the capital of Pakistan.

On Monday, Obama told the nation "the world is safer" with bin Laden dead. He also declared it a "good day for America."

House Minority Leader Nancy Pelosi (D-Calif.) said Monday she hoped a Congressional delegation could go to Ground Zero.

"As we go forward, I hope we will have a chance to speak about this on the floor in the form of a resolution, and perhaps go to New York in a joint session, as the New York delegation has suggested, in a way that is a much better occasion now that this historic event has taken place," she said.
