So it begins or rather continues. Barr is having Horowitz look into wiretaps for Carter Page, with a bevy of other related investigations into the 2016 spying into the Trump campaign. I think Barr suspects based on the progress of investigations so far, possible criminal conduct and the reason for assigning U.S. Connecticut prosecutor to the case. https://www.washingtontimes.com/news/2019/may/13/john-durham-appointed-william-barr-investigate-rus/ Also interesting is the NYT article of FBI sending an investigator posing as an assistant to meet with Papadopoulos. Supposedly that started the whole Russian collusion story on the Trump Campaign. Oh what a tangled web we weave, When first we practice to deceive.
