The Nevada Independent notes some details about the attorney representing the Fight for Nevada group:
The recall group’s attorney is Robert Barnes, a prominent Los Angeles attorney who is backing litigation challenging COVID-19 shutdown orders in several states. Barnes represented actor Wesley Snipes in a major tax case and more recently represented internet conspiracy theorist Alex Jones in a defamation and emotional distress lawsuit brought by the parent of a child killed during the 2013 Sandy Hook Elementary School mass shooting.
