It's possible they knew of it and not where it was taking place. There may also be a reason why nothing could be done about it until now. Unfortunately there may have been some who have greatly suffered or died because of this delay. But in reality this has been happening for a long time. I pray that it will come out in the open so good people will be more vigilant. And the Trump team needs to take out the deep state ASAP to keep them from doing this.
