Which president signed the fair sentencing act eliminating the mandatory minimum sentence for simple possession of crack and powder cocaine?

 The correct answer is :  Barack Obama

Explanacion:   It was a congressional law signed by Obama on August 3, 2010. This law eliminates the difference between the sentences for crack and cocaine.
