Longest Walk reaches goal

American-Indian group ends walk across USSome 500 American Indians are gathering near the White House to mark the end of a 8,300-mile walk across the nation.

The trek from San Francisco to Washington, D.C., aims to bring attention to the impact of global warming on the environment.

Organizer Ricardo Tapia says the Longest Walk 2 also was an effort to spotlight concerns among American Indians, such as the destruction of sacred sites by developers.

Organizers plan to present a manifesto of American Indian concerns to Democratic Congressman John Conyers of Michigan.

Actor and civil rights advocate Harry Belafonte is also scheduled to appear at a traditional pipe ceremony at the U.S. Capitol.
