Three Republican state lawmakers have been sued for blocking a liberal advocacy group on Twitter, preventing them from seeing comments from the lawmakers that others get to read. One Wisconsin Now accuses Assembly Speaker Robin Vos, finance chair John Nygren, and Representative Jesse Kremer of violating the First Amendment. Group leader Scot Ross says that if government officials create a public forum, everyone should get access — not just those they agree with. One Wisconsin Now has asked a federal judge to order the lawmakers to stop blocking the group, which often criticizes G-O-P policies on Twitter. In response, Kremer called himself “probably one of the most accessible statesmen in Wisconsin,” and he tweeted that he often has discussions on social media with people of opposing viewpoints. Vos and Nygren have not commented.
