However, less than an hour later, Leo's brother offered some conflicting information to Chicago's WGN News (video above):

"He was never, ever a Cubs fan, so I don't know where that came from. He was always a Sox fan. Our mother was a Cubs fan. I don't know, maybe that clued in there, and our dad was a Cardinals fan, so I don't know where that all came from. And all the aunts in our mom's family were from North Side, so that's why they were Cubs fans."
