Crow opposed the 2003 invasion of Iraq, wearing a shirt that read "I don't believe in your war, Mr. Bush!" during a performance on "Good Morning America" and posting an open letter explaining her opposition on her website. At a performance with Kid Rock at the 45th annual Grammy Awards, she wore a large peace sign and a guitar strap with the words "No War". She showed support for injured soldiers in 2003 by playing her guitar and singing to individual patients at Walter Reed Army Medical Center.
