Souter didn't even issue a statement. Kennedy did.
Even though I disagree with so many of Kennedy's opinions he has class unlike Souter I think him being out of the country has something to do with it. He would have found out Sunday morning and getting back by tuesday morning could be a little tricky. I'm sure he will be there for the funeral.
Souter and Kennedy will be at the funeral. The pressure was too much for Souter.
