David Cook Thanks Fans for Their Support

A couple days after Adam Cook, the brother of last year's American Idol champion, passed away, David Cook has reached out to fans.

Impressively, the singer took part in the Race for Hope in Washington, D.C. yesterday. On his My Space page, he says he never considered pulling out of the charitable event.

"My brother never wanted his illness to affect others," Cook writes. "That was evident in the fact that he wanted his illness to have no part in my experience on Idol, a point he was quite adamant about. So, with that wish in mind, I ran and was involved with the event as an homage to him.

"I want to again thank everyone who donated to the race and continues to donate, sent a kind email, posted thoughts and prayers, called, etc," Cook continues. "I take it as affirmation that my brother was the great man that I knew, and whose ideals I constantly try to uphold in myself. It is with those ideals in tow that I vow to continue to speak out in hopes of raising whatever necessary to help eliminate cancer entirely."
