San Antonio-area Republican congressional candidate Brandon Herrera is on the defensive after being named in the online manifesto left behind by the woman who this week shot up a Minneapolis church, killing two children and injuring 17 others. Mass shooter Robin Weston, 23, mentioned Herrera — an online gun influencer who posts videos under the handle the “AK Guy” — three times in an 11-minute video posted prior to the mass shooting. In the disturbing clip, Weston also showed off a cache of weapons, gulped down a beer and sporadically broke into laughter.
