A federal judge is allowing a free speech lawsuit against officials at the University of California, Berkeley to move forward although she says there is no evidence the school discriminated against campus speakers based on their conservative views. U.S. District Judge Maxine Chesney ruled on Wednesday, April 25, 2018, that the Berkeley College Republicans and Young America's Foundation could challenge alleged university restrictions on "high-profile" speakers and a $9,000 fee the school charged to host conservative commentator Ben Shapiro.
