Update 4-4-2017:NOM published photo of hate bus at US Capitol, this was apparently as close to GW as they dared to approach.Not sure when photo taken either.
On the 3rd of April, NOM's so-called "Free Speech Bus" also known as the "hate bus" for anti-Trangender images on its sides was due to appear in DC. A few anti-Transgender bigots showed up at George Washington University and attracted a student counterprotest leavened with counterinaugural veterans. They left after about an hour, with nobody having found the "Hate Bus," and were from an apparently unrelated group. There was no mention on NOM's twitter feed of even arriving in DC.
Video from the GWU counterprotest plus clip from Philly showing possible reason for hate bus no-show at GWU (1 min 3 sec)
