McCaskill to speak at Democratic convention

WASHINGTON - Sen. Claire McCaskill will be an opening night speaker at the Democratic Party's national convention in Denver.

The Missouri Democrat has been one of Barack Obama's biggest supporters in his quest to become the party's presidential nominee.

Michelle Obama and House Speaker Nancy Pelosi will be the featured first-night speakers on Aug. 25. The opening night theme is "One Nation."

Opening night speakers also include Denver Mayor John Hickenlooper and a videotaped message from Massachusetts Sen. Edward Kennedy.

McCaskill was the first woman in the U.S. Senate to endorse Obama and emerged as a key surrogate and adviser to his campaign.
