ROUGH CUT (NO REPORTER NARRATION)

STORY: Hundreds of immigrants crowded on to the National Mall on Tuesday in a rally to support immigration reform legislation introduced on Capitol Hill.

The rally coincided with the introduction of legislation that supporters hope could chart a path to citizenship for 11 million illegal residents.

Politicians, including House Minority Leader Nancy Pelosi, spoke to audience members who waved American flags and held up signs reading "Citizenship for 11 million."

"Si, se puede," Pelosi chanted from the stage.

Applause erupted from the crowd as the popular Mexican group "Los Tigres del Norte" began their performance.

The "Camino Americano: March for Immigration Reform" was allowed to proceed despite a government shutdown that has closed national parks across the country.

Veterans who entered the World War II Memorial last week also received permission to access the site from the National Park Service.
