I think that's the Cuomo's son playing " ass marshall". He's the Cuomo Hillary screwed over. He had been Clinton's HUD chief, and intended to run for New York Senator until Hillary wrecked his plans.
I can't find any articles to back me up on this..someone will correct me if I'm misremembering their history.
And...........I think this Cuomo, Andrew, might be running for Governor?????? that would explain his cozying up to Hillary despite their history.
