Yes guys, Adam Cook is no more. And just one day after losing his older brother to brain cancer, David Cook delivered a touching address when he was grand marshal of the 12th annual Race for Hope 5K run in Washington, D.C. He said before the crowd: “I actually lost my brother yesterday to a brain tumor, and I couldn’t imagine being anywhere else right now… I lost one today, but I gained 9,000, and I will be here every year that they will have me.” The co-chair of the charity race, Jeff Klodin told People magazine,

“David Cook is beyond the most courageous young person I have ever known. What he did this morning when he was dealing with the most raw emotion was incredible.”

Mr. Kolodin continued, “No one knew his brother had died, [and David spent the rest of the day] hugging survivors, signing autographs for them, taking pictures.” The American Idol champion had canceled a pair of concerts in March to go home and spend time with Adam. He also wrote “A DailyAntheM” in honor of his brother for his debut album. Adam Cook was a married father of 7-year-old twins. Our condolences to David Cook and his family.
