WASHINGTON (CNN) – To commemorate the 40th anniversary of his capture in North Vietnam, Sen. John McCain, R-Arizona, released a new ad Thursday mocking Sen. Hillary Clinton, D-New York, for seeking federal funds for a museum commemorating the Woodstock concerts.

"A few days ago, Sen. Clinton tried to spend one million dollars on the Woodstock concert museum," McCain said. "Now my friends, I wasn't there. I'm sure it was a cultural and pharmaceutical event. I was, I was tied up at the time."

The ad, which will air in New Hampshire, shows original video of McCain tied up and injured as a prisoner of war in North Vietnam. The Republican presidential candidate originally made the joke during a debate in Florida last weekend.

McCain will honor the anniversary on Friday in Iowa with Colonel Bud Day, who cared for him during his imprisonment. McCain was a prisoner of war at the infamous "Hanoi Hilton" in North Vietnam for five and a half years.
