It was actually confirmed in the article that MSW linked to but I suspected since I researched the Human Dignity Institute, which Bannon was invited to address in 2014.  http://www.dignitatishumanae.com/index.php/home/  It is splashed on their homepage.  Guess who is the head of the board - Ray Burke.  It is easy to put two and two together about who invited Bannon to speak.  

Oh and they are happy to advertise Bannon's speech unlike mainstream organizations who would be walking away from it especially given the criticism of the Anti-Defamation League.
