U.S. Olympic swimmer Ryan Lochte apologized Friday for his behavior surrounding an incident at a Rio de Janeiro gas station, saying he should have been more "careful and candid" about how he described what happened after a night of partying with his teammates.
But he didn't explain why he embellished details of an encounter with armed security guards and called it a robbery, and why he left out that he and three teammates had vandalized a gas station restroom.
