I am sorry but isn’t the point of a “bus” tour, as opposed to flying, so you can do stops along the way and meet people and give speeches.
It seems like they just drove straight thru, which makes the whole thing incredibly bogus.
No way HRC rode that van from New York. She would travel private jet and they would meet at different locales.
Second, I will bet that there are at least two vans.
Got some really dark glass-—maybe illegal-— so the riders can’t be seen.
