AUSTIN — In an expletive-filled Instagram post on Wednesday, Texas State Sen. Roland Gutierrez accused his Republican colleagues of being out of their minds for passing a bill that will allow horse dewormer ivermectin to be sold over the counter at Texas pharmacies. “It is incredible that this shit is actually happening right now in the Texas Senate, but that’s your Republican Party at work,” said Gutierrez, a former San Antonio councilman who’s gained a reputation as one of the chamber’s most outspoken Democrats. “That’s what’s happening in Texas: these fuckers are crazy.”
