Phil Mickelson is on the witness list for the defense in the ongoing insider trading trial of Las Vegas businessman and renowned sports bettor William "Billy" Walters, but it is not known whether the professional golfer will take the stand as the trial heads into its second week in New York.
Walters is charged with conspiracy and securities fraud, stemming from a series of stock trades made in 2012, involving Dallas-based dairy company Dean Foods. The government alleges Walters received inside information from former Dean Foods executive Thomas Davis and passed tips along to friends, including Mickelson.
