From TPM Reader DR:

Here's an obvious talking point for the Dems that I'm sure they won't exploit.

Back in August, the administration suggested that if Congress didn't pass the "terrorist surveillance" eavesdropping bill before going into recess, the country would actually be in danger of attack. Now, though, Bush says he'll veto the renewal bill if it lacks retroactive telco immunity. So Bush is now holding the country's security hostage to get telco immunity?! Why is telco immunity more important than listening to terrorists?

Or, put more bluntly, what's he trying to hide?
