7. I assume you won't be deterred by the truth but I'll try (again and again and again. ..)

Jeffrey Sachs says he only helped Sorondo reach out to Bernie Sanders. It waa Sorondo's idea to invite Sanders.

 
The chancellor of the body, Monsignor Marcelo Sanchez Sorondo, ...said that it was his idea to invite Sanders.  

Jeffrey Sachs, a Columbia University professor who is presenting at the event, said in a phone interview that he helped the Vatican reach out to Bernie Sanders in March, and he doesn’t know why Archer alleged that the Sanders campaign initiated the gig. “The academy sent the invitation, it’s pure and simple,” he said. “A lot of people in the Vatican respect him a lot. He is speaking in the same kind of moral themes that Pope Francis, and the social teachings of the Church, promote, which is a moral economy.” A representative who works with Sachs also passed along an official invitation from Sanchez Sorondo to Sanders dated on March 30.
