Two notable court proceedings involving former President Trump, one historic day.  Day 7 of the former President's criminal hush money trial saw former National Enquirer publisher David Pecker describing to the court how he paid for Karen McDougal's story to keep her quiet about her alleged affair with Trump, and in Washington DC the Supreme Court heard arguments for and against making any former President immune from criminal prosecution for acts in office. Anderson Cooper in New York, and Kaitlan Collins from Washington DC present CNN's special primetime coverage, breaking down both events.  Kaitlan interviews one of the attorneys representing Donald Trump in the immunity case, Will Scharf, who was at today's Supreme Court arguments. Plus, Anderson speaks to Rachel Goldberg and Jon Polin, whose son Hersh was seen for the first time since the Oct. 7 attacks in a Hamas-released video this week.
