As much as I hate to say it, I think that the White House was in a bit of a conundrum about what to serve at the Clemson event. If you serve caviar, foie gras and filet mignon, you will get criticized for feasting in luxury as 800,000 federal employees are being forced to go to food banks. If you serve McDonalds, pizza, etc., you come off as being a cheapskate and diminishing the grandeur of the White House.
I don't know why they couldn't have tried something in-between. Maybe some gourmet sandwiches, salads, hors d'ouevres, etc. Are the White House chefs part of the shutdown?
Still, given the choices, they elected to go low. Cold fast food served on silver plates...
I'm sure those top athletes appreciated the opportunity to dine on filet-o-fish sandwiches and other fine fare.
