Lots of political candidates use footage of their opponents in TV ads, but Fox News isn't too happy that Missouri Democratic Senate Candidate Robin Carnahan is using Fox footage of her opponent, Rep.

Fox News Network has filed a lawsuit against Democratic Senate hopeful Robin Carnahan over use of station footage in an ad attacking her Republican rival.
