John, from my understanding the Vets were invited. There are however many Tweets, FB post, and even articles written about White people in particular women disrespecting elders and treating the protest and protectors as somewhat of a vacation and exotics to be with. They have also reported that these same people are taking supplies and doing their fair share of work. This is the issue with many movements when White folks overstepping their boundaries instead of being allies they want to take over. If Bernie decides to run in 2020, hopefully, he will implement the lessons he learned in reference to race in this election.
