Griffin’s Chicago residences have been in buildings known for luxury. After selling his place in Lake Point Tower, he now owns the penthouse in the Park Hyatt and a condominium in the same building that houses the Four Seasons Hotel. In the past two years, he has bought four out-of-state properties: a floor of a building overlooking New York’s Central Park; a mansion in Aspen; and a vacation home—as well as a separate parcel of land—on Hawaii’s Big Island. The combined cost of these four properties is comparable to the budget of the government of the South Pacific island nation of Vanuatu.

OK, Bitter in Albany Park. Did you happen to actually read the article and take note of the charitable contributions that this man and his wife have made? Maybe you should look before you leap.

I used to work at cig several years back and even had lunch with Mr Griffin. Tough place. But I learned a lot and was paid fairly. Very beneficial for my career. I admire Mr Griffin. The US needs more of his type. Very intelligent and hard driving and focused man. He works hard and is motivated and surrounds himself with like mnded people.

For what it's worth, I know for a fact he entertains young women around the Chicagoland area and fly's them out to Aspen as prostitutes,
