"It has been a difficult decision, but I've decided to leave this amazing experience in the middle of August and transition to the next stage of my life," he wrote in the letter, according to CNN. "I'm so grateful to the Vice President for trusting me with this privilege and was honored to support the President's and Vice President's tireless, committed and historic work."
