Vice President Kamala Harris made a surprise appearance at the Pride event in Washington on Saturday but it was one of her protectors who drew the attention of many Twitter users. Any time a president or vice president mingles with the public becomes a challenge for those charged with guarding them – simply because the situation is less under security’s control. Much of the Twitter attention was directed at a Secret Service agent near the vice president, a tall man in sunglasses who was seen behind Harris in photos and videos as she traversed the parade area.
