A explosive new ad says Rep. Gabrielle Giffords (D-Ariz.) supports legislation giving terrorists the same rights U.S. citizens enjoy in courts, depicting captured al Qaeda leader Khalid Sheikh Mohammed as an example.

The ad from Giffords's challenger, state Sen. Tim Bee, links the Arizona representative with House Speaker Nancy Pelosi on legislation, including H.R. 2826, the bill the ad says would give terrorists rights in court.

"Pelosi supports Giffords's bill to allow captured terrorists to be tied in our courts with full legal rights of American citizens," the ad says, while depicting the famous photo of Mohammed, called the "principal architect of the 9/11 attacks" by the 9/11 commission reports.

The link to the al Qaeda leader is part of a larger ad seeking to tie Giffords to a number of other plans supported by Pelosi. The Cook Political Report rates the race "lean Democratic."
