There are some unusual things about that incident.
The chef’s family was visiting him on Martha’s Vineyard that weekend. The Obama’s had canceled their dinner at home to dine out. Yet the chef didn’t go visit his family, but went paddle boarding with a Secret Service agent. Why is the Secret Service agent leaving the house to go paddle boarding? Why was the chef not wearing a life vest? There was a video of him learning to swim in a pool; apparently he was able to swim one whole length of the pool.
