From Bearing Arms:

Maryland Democratic Party Secretary Robbie Leonard took to social media to post photos from a Maryland House Judiciary Committee meeting in late February, where gun rights activists wore “We Will Not Comply” shirts during the hearing on additional gun control measures, along with a message calling the advocates “homegrown terrorists” and calling on his followers to “dox” them.
“I hope the FBI runs the name of every witness who is wearing a t-shirt that says ‘We Will Not Comply,’ Leonard said in one Facebook message. “They’re a bunch of terrorists in the making.”
