Roy Blunt, Missouri GOP Rep. And Senate Candidate, Scrubs Graphic 9/11 Campaign Video

SEDALIA, Mo. -- A Republican congressman running for the U.S. Senate in Missouri has taken down an Internet video showing World Trade Center rubble and an assertion that his Democratic opponent won't oppose building a mosque near the site.

Rep. Roy Blunt said Thursday he wasn't aware the video had been posted overnight on his campaign's YouTube site. He said it was distracting from a discussion of issues.

Robin Carnahan, who is Missouri's secretary of state, called the video a shameful exploitation of the Sept. 11 attacks.

Blunt's campaign changed the video Thursday to show a photo of Carnahan with President Barack Obama. It still includes a clip of Carnahan saying she doesn't want to tell New Yorkers whether a mosque should be built near ground zero.
