Ambassador Joe Wilson and wife, Valerie Plame, appear in new Clinton ad

WASHINGTON (CNN) - Hillary Clinton's campaign released a new ad in Oregon Friday, featuring two familiar faces: Ambassador Joe Wilson and his wife, Valerie Plame, who was the undercover operative in the highly publicized CIA leak case.

In the ad, they say Clinton has the "strongest plan to end the Iraq War and bring our troops home safely," according to the campaign.

The 30-second ad, dubbed "Strongest Plan," comes as Oregonians vote by mail in advance of the state's May 20 primary.

The Clinton campaign says the Wilsons played a "critical role in drawing attention to the Bush Administration's exaggerated claims about weapons of mass destruction in Iraq, and have been outspoken critics of the conduct of the war."
