CNN anchor Anderson Cooper "will report his first story for 60 Minutes" this Sunday, CBS announced today.

Cooper's report features Joe Darby, "the man who touched off one of the biggest news stories of the war in Iraq when he gave authorities pictures of U.S. soldiers abusing Iraqi prisoners at the Abu Ghraib prison." Cooper already covered Darby on his CNN program -- Randi Kaye's piece aired on 360 in August.

Cooper had two reports on 60 Minutes II in 2004-05. He signed a deal with 60 Minutes last spring.
