When School Starts And Your Sub Teacher Is Barack Obama

While McKinley Tech students in Washington, D.C., were still settling into a new year of classes Friday, in walked the former president of the United States.

Barack Obama strolled in, casually asked if the high schoolers minded him crashing their class and then waited for the shock waves to subside.

The former president then spoke to the students about why he strived to engage with people their age during his eight years in office.

“One of the things I did throughout my presidency was I’d meet with groups of young people everywhere I went, whether it was here in the United States or when I was traveling overseas,” Obama told the teenagers. “Just to kind of hear from them, find out what they’re interested in, because I do believe that most of the problems we have are going to be solved by you.”

Obama posted video and photos of his day out on Instagram andTwitter.
