WASHINGTON - People gathered today to celebrate the 50th anniversary of Martin Luther King Jr.'s "I Have a Dream" speech.

Dignitaries from all races and creeds spoke at the Lincoln Memorial in Washington, D.C., including Oprah Winfrey, Caroline Kennedy, former President Bill Clinton and President Barack Obama.

An estimated 250,000 people attended the March on Washington half a century ago.

Seniors at the Kittay House in the Bronx say it feels like just yesterday that King gave the historic speech. Residents say his powerful words had a great impact on them.
