是的，這和聯邦政府沒有半毛關係：

Q: Does the U.S. government fund the U.S. Olympic Team?

A: No, the federal government does not fund Team USA’s Olympians. The United States Olympic & Paralympic Committee receives no federal funding for Olympic athletes or programs.

Q:  Who pays for Team USA Athletes?

A: Team USA is proudly fan-funded! Our athletes are generously supported by sponsors and donors who help them make their dreams a reality.
