No, but they are barred from meeting each other when Clinton's wife is under investigation.  And these two weren't that close.  They didn't "run into each other", they met in secret onboard an jet sitting on the tarmac after Lynch held her flight to make time to meet Bill Clinton.  The appearance of impropriety is the smoke of a massive conflagration.  Had it not been for a single eagle-eyed reporter, no one would have ever known the meeting took place.  And here I thought transparency was important to these people.
