If it comes out that Obama did bug the cloak room phones, then that would mean he was listening on Democrats as well as Republicans. They aren’t going to stand for it. That’s why if this congressman has evidence of the bugging then he needs to produce it.
At this point we don’t know if the story is true. I wouldn’t put it past the Obama administration, but it may be impossible to find any evidence implicating Obama personally. There won’t be a written order or email or a taped conversation.
