Billie Jean King says she now believes that athletes should think twice about protesting for gay rights at the 2014 Sochi Olympics.
The former tennis great, who will be part of the official U.S. delegation, cited Rule 50 of the Olympic Charter, which bans political demonstrations by participants at the Games.
"I don't want any athlete getting in trouble, although I think they should do anything they want," King told the Associated Press. "Before I knew about Rule 50, I thought it would be sweet to wave some flags or something. But they can get in big trouble and have their medal taken away and also be sent home."
Gay rights have become an issue in Sochi because of recent Russian legislation that criminalizes discussion of "nontraditional sexual relations" in the presence of minors. The law effectively bans gay pride parades and other forms of speech.
