Shortly after Obama arrived at the restaurant, more than 100 protesters calling for justice for Michael Brown, the shooting victim in Ferguson, Missouri, marched down M Street in what appeared to be a previously planned demonstration.

Before their date, the president spent four hours playing golf at Andrews Air Force Base.

Obama and his wife traveled separately on Friday, prompting a delayed date night.

Both alluded to their anniversary Friday at their respective stops. "I might not even see him today," Mrs. Obama told a Boston political gathering. "Twenty-two years she's been putting up with me," her husband told steel workers at a plant in Princeton, Indiana.
