(SportsNetwork.com) - Phil Mickelson is reportedly one of three people being investigated by the Federal Bureau of Investigation and the Securities and Exchange Commission for a major insider-trading violation.
The Wall Street Journal reported on Friday that Mickelson, Carl Icahn and William Walters potentially used illicit information to profit from trades on Wall Street.
The newspaper states Walters, who is a well-known Las Vegas bettor, possibly passed nonpublic information received from Icahn to Mickelson and the two used the information for profit.
Mickelson and Walters are known to play golf together, while Icahn has denied knowing Mickelson in any way.
Mickelson was approached by FBI agents on Thursday following his opening round at the Memorial Tournament, but he referred them to his lawyer.
"I can't really go into much right now, but as I said in my statement, I have done absolutely nothing wrong," said Mickelson, after shooting an even-par 72 on Saturday at the Memorial. "And that's why I've been fully cooperating with the FBI agents, and I'm happy to do in the future, too, until this gets resolved."
No charges have been filed against any of the three people being investigated.
"It's not going to change the way I carry myself," Mickelson said. "Honestly, I've done nothing wrong. I'm not going to walk around any other way."
