LIV Golf is coming to Trump National Golf Club in Bedminster, New Jersey, today, which is just about an hour west of New York City. The Saudi sovereign wealth fund-backed league continues to take the golf world by storm, landing American golf superstar Bubba Watson this week. 

But victims of the Sept. 11 attacks and their families are protesting the league’s event due to the Saudi government’s alleged connection to the tragedy. Tim Frolich, who survived the attack in 2001, said that golfers should consider this before taking LIV Golf’s huge payouts. 

“It’s disgusting golfers decided to do business with the Saudi kingdom,” Frolich told Al-Monitor. “I don’t believe anyone should do business with the Saudi government until they understand who plotted and executed 9/11.” 

LIV Golf burst onto the golf scene earlier this year, peeling away big names such as Phil Mickelson, Dustin Johnson and Sergio Garcia from the PGA Tour, which is the dominant competition in the United States. LIV Golf has reportedly offered top golfers hundreds of millions of dollars to join. The league also pays considerably higher guaranteed money than the PGA Tour, making it especially attractive to lesser-known golfers who have not made millions playing the sport.
