After a long battle with brain cancer, Adam -- the brother of "American Idol" winner David Cook -- has died at a hospice. He was 36.
"I actually lost my brother yesterday to a brain tumor, and I couldn't imagine being anywhere else right now," Cook told the crowd on Sunday at the 12th Annual Race for Hope 5K event in Washington, D.C. -- a benefit for brain cancer research. "I lost one today, but I gained 9,000, and I will be here every year that they will have me."
According to reports, Adam died at 1 AM today in Terre Haute, IN.
Adam is survived by his wife Kendra and their children.
