No wonder Sonny skied into a tree! LOL
From Wiki
Chaz Bono’s paternal relationship became strained after Sonny became a Republican Congressman from California. The differences in their political views separated them, and the two had not spoken for more than a year at the time of Sonny’s fatal skiing accident in January 1998.
(Apparently, Sonny was more supportive of her lesbian *coming out* than Cher. He didn’t live to see her gender surgery)
