Photos have surfaced of Barack Obama serving as a groomsmen in his longtime aide’s wedding.

The president flew down to Jacksonville, Fla. on Air Force One last Saturday after he was asked to be a groomsmen in Marvin Nicholson and Helen Pajcic’s wedding.

Nicholson is the White House trip director and a personal aide to the president. The two have also regularly golfed together.

Though the wedding was closed to the media, photos surfaced on social media this week.

Secretary of State John Kerry officiated the wedding.
