Phil Mickelson denies any wrongdoings in insider trading being investigated by FBI

American golf ace Phil Mickelson, who is one of the US's richest and most-admired sportsmen, has reportedly denied any wrongdoing in insider trading after the FBI launched an investigation into the same.

Mickelson said that he was co-operating with the government inquiry as he along with investor Carl Icahn and William Walters, who is a high-profile gambler, are being investigated for possible illegal share sales, using information given by Icahn.

According to the BBC, Icahn has also denied any wrongdoing in the matter, while Walters has yet to comment on the issue.

A source familiar with the investigation reportedly revealed that none of the men had so far been accused of any wrongdoing.

The FBI, along with the Securities and Exchange Commission and federal prosecutors in Manhattan, are said to be looking into trading in two different stocks, with one line of inquiry focusing on trades in cleaning products company Clorox.

Icahn, who is a billionaire investor and prominent activist, had reportedly been mounting a takeover bid for Clorox around the time that Mickelson and Walters placed their trades.

Investigators are reportedly examining whether Icahn discussed his bid with Walters and if the gambler relayed that information to Mickelson.
