Kind of an interesting conundrum. What comes out in the trial will likely look bad on the US, mainly the tourture, but the plea deal could be a liability for the current admin, since they'd be accused of being soft on terrorism.
ETA: Plus more could come out about the security failures of 9/11 which could be pretty embarrassing to the US.
I don't see a ton of value to a Fox and NBC debate. ABC and even CNN at this point are considerably less biased.
