From the official George Washington University announcement page:

Apple CEO Tim Cook will deliver the George Washington University’s commencement address May 17 and will be awarded an honorary doctorate of public service, the university announced Wednesday night.

Mr. Cook, whose invitation was suggested by GW students during the nominating process, has led Apple since 2011.

“I am delighted that Tim Cook has accepted our invitation to give this year’s commencement address on the National Mall,” George Washington President Steven Knapp said. “I know our graduating students will be inspired and enlightened by his reflections on the lessons he has garnered from his distinguished career as a highly effective leader at the forefront of technological innovation.”

By far the best part of this is the video showing the back and forth between the school and Tim Cook. The video is so well done, I suspect that Apple made it. Take a look.
