President Obama delivered his final Veterans Day address at Arlington National Cemetery on Friday, during which he reflected on the tumultuous election that came to an end this week and emphasized the need for unity once more.

“Last time I stood on these hallowed grounds on Memorial Day, our country came together to honor those who have fought and died for our flag,” Obama, flanked by Veterans Affairs Secretary Robert McDonald, honor guards and retired service members, told a crowd of veterans gathered for the somber occasion.
