Clowns operation, planned long in advance. This is the Demoncrats October Surprise. The guy is a career criminal with a shady past and registered Demoncrats until 2016. He needs money as well. He is hand picked by C_A, he is sent to rallies to be photographed for a background story. Has stickers put all over the van that everyone know could not have been driven without being stopped by PD. Photographed van to have background story as well. Mail bombs would not have made through the USPS, everyone knows that in addition to the lack of postage cancellation. "Pipe Bombs" were all planned and planted by Demoncrats and clown factions left in C_A. The only reason I can think of as to why Wray and Sessions would go with the "through the USPS story" is for disinformation.
JUST my opinion
