"I actually lost my brother yesterday to a brain tumor and I couldn't imagine being anywhere else right now," Cook, 26, told the crowd at the benefit for brain cancer research. Adam Cook, 36, had been fighting the disease for a decade, but thankfully at least had the opportunity to see his little brother perform on Idol.
Per Entertainment Weekly, fans can make donations to David's Race for Hope team through September 30.
