A controversial professional golf tour backed by Saudi Arabia tees off on Thursday. Today, two-time Major winner Dustin Johnson announced he's resigned from the PGA Tour ahead of headlining the Saudi-backed tour, called the LIV Golf Invitation Series. The announcement comes as the PGA tour has threatened disciplinary action for its golfers who take part in the Saudi golf league event, which will also feature notable golf stars like Phil Mickelson and Sergio Garcia; however, LIV Golf's CEO, Greg Norman, told The Washington Post that Tiger Woods rejected a contract worth 'high nine digits' to play in the tour. Chris Bumbaca, reporter for USA Today Sports, joins Cheddar News' Closing Bell to discuss.
