The Obama family is busy doing what a lot of other families are doing this time of year. They are attending school events with their children.
The first parents traveled to Sidwell Friends School in Bethesda, Md., for a morning event with Sasha. About 10 hours later -- after several White House meetings and a trip to the State Department -- the president joined Mrs. Obama and her mother, Marian Robinson, at the Sidwell school Malia attends in northwest Washington.
On the way home, the Obamas encountered a slight delay.
Secret Service officers had to subdue two men who refused to get out of the street when the presidential motorcade came through.
The men were charged with assaulting a police officer and failure to obey a lawful order. Their names have not been released.
Secret Service spokesman Ed Donovan said the incident appeared to be a random event and not an organized attempt to block the president's motorcade.
