Ryan Lochte Lied to U.S. Olympic Committee & is Ready to Apologize

Ryan Lochte told the U.S. Olympic Committee the same lie he told NBC, and he now faces possible discipline in addition to criminal charges ... TMZ has learned.

Sources close to Lochte and familiar with the situation tell us, Ryan repeated the story to USOC officials ... that he and his fellow swimmers were in a cab going back to the Olympic Village when men posing as cops robbed them and took their wallets.

The USOC and the IOC took heat Sunday after Lochte told the lie on TV. However, we're told once it heard the reports, the USOC got in touch with Ryan immediately, who said the story was untrue and the USOC passed that info to the IOC.

We've now learned after Lochte went on TV, USOC officials talked to him and he repeated the concocted story line and verse.

TMZ has also learned Lochte is preparing an apology to the U.S. and Brazil.
