U.S. Soccer’s decision on Wednesday to sue the union representing the world champion United States women’s national team came as a surprise to some of the players, many of whom were gathering in Texas for an Olympic qualifying tournament next week.

But the players’ discovery that U.S. Soccer’s court filing included detailed personal information about many of them — including the home addresses of more than two dozen players and the personal email accounts of some of the team’s most prominent players — brought a different reaction: outrage.

“Naturally, we’re upset,” midfielder Megan Rapinoe said Thursday. “The players are very, very upset. We feel disrespected. We feel that our personal information, our privacy and our safety was handled frivolously and with real negligence. I doubt it was purposeful, but it’s an egregious error, and one that’s unacceptable.

“We’re public figures. There have been issues of privacy and hacking and stalkers — it’s very unsettling. We’re upset. To know that someone could show up at your door? That’s extremely unsettling, and it’s something that you can’t get back.”
