The former director of the FBI (Federal Bureau of investigation) may be focus of investigation of leak of classified information about the Russia Investigation.
It is easy to understand this focus as previously Comey had access to the information and had previously leaked notes of his personal interactions with President Trump.
It would not be a stretch of the imagination that Comey would leak other information. If he was able to do it once, he might have felt emboldened to do it again.
Alas we will have to wait and see what comes of the investigation. But, it seems like some o FCC the media leaks are now being investigated.
