Vice President Pence was so outraged (outraged!) that he spontaneously left the stadium when a few players kneeled during the anthem.
Of course, he kept the press outside the stadium because he knew he probably would be leaving "very early" and the president later tweeted that he sent him there to do this. It was strictly a pre-meditated publicity stunt.
That trip to Indy probably cost the taxpayers close to a million dollars.
