I'm not saying to completely dismiss it, but, keep a few things in mind.

Firstly, there is no evidence from the CIA regarding the election hacks. There are anonymous sources who claim to work with/in the CIA and/or have information from the CIA.

Secondly, I'm not saying to outright dismiss it, but, that you need to frame the information in the context of their success rate. (and, no, you don't get to consider secret unknowable wins in that calculation)
