Are we talking like he likes a game of poker" Trish Johnson responded.Kaufman then mentioned Brooks Koepka, calling him a 'Smash GC kinda guy.' He explained that these were the names of their respective teams.Johnson, while acting as though he was unfamiliar with this new information, asked:"What's that all about? That's not golf, what you talking about?""Just filing in people that may want to know," Kaufman answered.For the uninitiated, LIV Golf has been quite controversial, as many golf fans have accused the league of sports washing by Saudi Arabia.
