The Supreme Court heard oral arguments today on Donald Trump's claim that presidential immunity shields him from prosecution. While that hearing was underway, the former president was in a Manhattan courtroom where his longtime ally David Pecker continued testifying in Trump's first criminal trial. Also, protests against the war in Gaza rock college campuses and the University of Southern California moves to cancel its main graduation ceremony. Joyce Vance, Josh Gerstein, Mark Joseph Stern, Peter Baker, Brendan Buck, and Donna Edwards join.
