Breitbart found a blog-post from Tom Perrin, a neighbor of Bill Ayers and Bernadine Dohrn, that claims then-Senator Obama went to a barbeque hosted by Ayers and Dohrn. After they were contacted by Joel Pollack, the blog post was deleted. Fortunately, this snapshot had already been taken.
Another source also told Breitbart News, “I too saw Obama at a picnic table in the Ayers/Dohrn backyard, munching away — on the 4th of July.”
