Apropos of reports that Trump adviser Erik Prince has coordinated the infiltration of left-leaning organizations and movements—possibly to instigate incidents that wouldn't have occurred otherwise—here's evidence Prince definitely had an interest in what was going on in Portland: 
PS/ Hat tip to longtime Erik Prince business associate Gregg Smith (@10milesbadroad).
PS2/ Ironically, the more on-brand version of the tee isn't the one branded "Blackwater"—a firm Prince sold but clearly retains an affiliation with—but the "Portland or Bust" tee showing Portland on fire, exactly the sort of event Prince would celebrate and if possible encourage.
PS3/ Keep in mind this is a site serving the guns-and-ammo needs of paramilitary enthusiasts on the far right, so selling apparel declaring "Portland or Bust" (hitchhiker shorthand for "headed that way no matter what") and showing the result being Portland on fire is...*telling*.
PS4/ Here's a close-up of one side of the tee shirt Blackwater is selling for $23 (even as the Blackwater website continues to unctuously lionize Erik Prince, feting him as though he is very much still atop the organization and/or somehow absolutely essential to its operations):
PS5/ It's remarkable that even as Prince stands accused in major media of seeking to aid Trump in infiltrating left-wing movements to make them seem violent an entity doing business under Prince's name, likeness and image is selling merch associating such movements with violence.
