It's one beck of a coincidence. Not saying it's more than just a completely random event involving a private chartered train of GOP reps going to an annual retreat where their itinery was known well in advance, coincidetally just after a major vote to expose epic levels of FBI and deep state corruption and circumventing the constitution, after attending a popular and successful state of the union.
The deep state is perfectly happy, no drama going on there and definitely wouldn't want to intimidate or send a message,
But, yes I'm sure it's just a completely random, one in a million coincidental events where the outcome will undoubtedly be human error (blame the truck driver) or mechanical failure (the crossing gate arms not functioning properly) nothing more nefarious....
