ABC's Sunlen Miller reports:
As the President began his statement announcing the death of Osama bin Laden inside the White House, a large crowd of people, about 200 and growing, had gathered outside the White House gates on Pennsylvania Avenue, waving flags and dancing.
They sang the "Star Spangled Banner" in unison and chanting "USA! USA! USA!"
They also just sang, "Na na na na -- na na na na ...Hey hey goodbye" in reference to Osama bin Laden.
The crowd is swelling by the minute. People are running to join the group with American flags and there is lots of dancing and cheering. Complete jubilation.
