ICAHN: I've Never Given Out Inside Information, I've Never Met Phil Mickelson, The WSJ Story Is Irresponsible

According to the WSJ and then later Reuters, the FBI and the SEC are investigating activist investor Carl Icahn, pro golfer Phil Mickelson, and gambler William Walters for insider trading involving private information provided by Icahn.

However, Icahn has told CNBC's Scott Wapner that he had no idea what was going on.

"I have never given out inside information," said Icahn. "The WSJ story is irresponsible ... We've neer heard from the FBI and have gotten no subpoenas ... We don't know of any investigations."

Icahn also told Wapner that he didn't know Walters. While he knew of Mickelson, he said he had never met him.

In a followup with Reuters, however, Mickelson suggested that he was involved in an investigation.

"I have done absolutely nothing wrong," Mickelson according to Reuters. "I have cooperated with the government in this investigation and will continue to do so. I wish I could fully discuss this matter, but under the current circumstances it's just not possible."

This obviously isn't the end of this story.
