@lawfaremedia.org has notβ€”and we will not.

A moment of silence for the loss of Ella Cook & Mukhammad Aziz Umurzokov, two promising bright lights whose lives were tragically cut short by a mass-shooter. And a moment of solidarity with the entire Brown University, Providence, and Rhode Island community.

California political players are concerned after FBI says it’s been listening Dozens of players on the California political scene received letters from the FBI, letting them know the agency had been listening to them.

FBI wiretap notices in misuse of campaign funds in California show the importance of notice as a constitutional protection for electronic searches, even as they make Sacramento insiders nervous, I tell @straightarrownews.bsky.social @danlevincomedy.bsky.social san.com/cc/californi...

Brown to confer honorary degrees on seven distinguished leaders at Commencement 2025 The University will bestow honorary degrees on a diverse group of community leaders, artists, writers, performers and scholars during its Commencement exercises on Sunday, May 25.

It’s a special honor to be among those receiving honorary degrees from Brown. It’s a place that welcomed me and shaped me and challenged me and liberated me, and made possible everything that came after. I’m looking forward to celebrating this weekend with friends.
