If you remember, trump dropped the "Hillary Investigation" right after he was elected, before he even took office. It was, as everyone knew, a pack of lies designed to deceive his "silent majority", errrr, "brainless minority" into voting for him.
You know who else had private servers while serving as head of the state department? Rice and Powell. But only democrats can break the law I guess. Oh, and it wasn't against the law. There wasn't a law on the books about it unlike Trump's stealing America's secrets of which there have been laws since the 50's and 60's.
In the coming weeks, we can expect to hear Trump supporters running a lot of interference about "Hillary's emails."; We can further expect that precisely zero will note the fact that Clinton gave the server back when asked, fully cooperated with the FBI investigation, and was cleared. And that the Trump administration had ample opportunity to reopen that case if there was anything there to prosecute.
