Over the past decade or so, I have written quite a bit about Supreme Court leaks. For a time, Joan Biskupic had the inside scoop. Indeed, Biskupic relayed in her books that she had private conversations with the Justices. I've heard that Chief Justice Roberts, in particular, felt burned that Biskupic published information that was supposed to be off-the-record. So it goes. But after Justice Ginsburg's death, Biskupic's information largely dried up. Of course, Josh Gerstein at Politico got the Dobbs leak, but that was a one-off. Gerstein has not published any more inside information. More recently, Jodi Kantor of the New York Times has published a regular stream of information from the Court.
No matter how you slice it, the problem of leaks continues.
Justices Kagan and Barrett addressed the issue of leaks at some length during their congressional testimony (which I am just now wrapping up).
