Gary Gensler, the Chairman of the US Securities and Exchange Commission (SEC). Here's a statement from him regarding XRP:
"Many of these tokens are being offered and sold as securities... The American public is investing in these tokens... We need to ensure that those markets are fair, orderly, and efficient."
However, I found a more specific statement from Gary Gensler regarding XRP:
"I think it's fair to say that Ripple's XRP will be considered a security... Many of these tokens, including XRP, are being used as a means of raising capital for the development of a network or a project."
