Both President Barack Obama and his wife Michelle have been known to stop by local D.C. schools to visit with area students over the last year, but today was the first day the President visited a school in Maryland, according to the Post. Obama made a surprise to the lunchroom at Viers Mill Elementary School in Silver Spring today. He reportedly spent about 30 to 45 minutes chatting with 3rd and 5th graders at the school about what books they were reading.
