“You treat everybody similarly and with respect. Bernie Sanders may show up at the Democratic cocktail party on April 11. If he shows up, Bob Brady and I have discussed it, I think if he wants to speak we should let him speak. We should say city committees endorsed Hillary Clinton but we appreciate what you’ve done. You’ve brought a lot of new voters into the polls. You’ve raised some very important issues. You railed against the Democratic establishment, but there are 3500 Democratic committeemen who work for the party and don’t get a dime for it and we’re party of the Democratic establishment Senator. So, you’re happy to address us, but we’re for Hillary.”
