Was brought to my Ttention today.
Did YOU know Sessions was inveztigating this?
I was aware that the loophole that was being used for this purpose was being closed, but despite the sensational article you cited there's still nothing indicating an actual "investigation" into previous possible abuses was under way last summer, much less underway now. According to the original article on Brietbart, who broke the actual true story, Sessions asked for examples of previous utilizations, in order to help ensure the new policy was correctly implemented to prohibit them going forward. Here's Sessions' specific letter that Brietbart linked where he states exactly that. It's PDF or I would copy and paste the contents out for you, but there's no mention of any intent to start an actual investigation, in the letter from back then, or from anyone else since.
