Nope. The FBI still has an open investigation regarding the Clinton Foundation. She is under investigation regardless of the status of the email investigation.
I immediately thought about that too. It’s a very technical question. Does the probe into the Clinton Foundation include a probe into Ms. Clinton.
There's also an open investigation at the IRS. It hasn't gotten the front page headlines, but it's happening:
The Dallas IRS Office That's Quietly Determining the Fate of the Clinton Foundation
Bingo. The truth is an absolute defense in any libel suit.
And she would argue that it is the Foundation (and not she) who is technically ‘under investigation’. Guess what? She could probably get a jury or judge to rule that way. Not that this threat is meant to do anything other than stiffen her weak-kneed support. As such it’s just P-R.
