Even though Obama voted for a provision to strip out the immunity for the bad actors in telecom from the 2008 iteration of FISA, not enough of his colleagues -- especially the centrist ones whose support he's more recently been trying to get on healthcare -- decided to go along with him. Let's say Obama's Justice Department has evidence that such conservative Democrats were lobbied by telecom companies prior to voting for retroactive immunity. I'm sure there's some pressure there to keep such information -- should it exist -- quiet for as long as possible. At least until healthcare reform is pushed through. Or maybe until the major components of the PATRIOT Act are reaffirmed?
