I watched the segment... Based on his remarks it sounds like they have a lot of tape to review
It doesn’t sound as if the tapes themselves have a “smoking gun “ like illegal or immoral activity, but they contain footage of Obama with people who are known commies, socialist, radicals
Birds of a feather type of connection
Just my guess
Obama came out and said (maybe in his book) that he sought those types out. He made a choice.
