A federal judge placed limits on special counsel John Durham’s evidence in court meant to demonstrate a “joint venture” involving Hillary Clinton’s 2016 presidential campaign to discredit rival Donald Trump with Russian collusion claims.

A ruling Saturday evening included wins and losses for both the prosecution and defense in the case against Democratic cybersecurity lawyer Michael Sussmann, who was indicted for allegedly concealing his clients, Clinton’s campaign and “Tech Executive-1” Rodney Joffe, from FBI general counsel James Baker in September 2016 when he presented internet data that suggested a now-discredited back channel between the Trump Organization and Russia’s Alfa-Bank. Sussmann has pleaded not guilty.
