Phil Mickelson sends chilling warning to PGA Tour after PGA Championship

Phil Mickelson had a quiet week on the course at the 2023 PGA Championship.

The six-time major champion wasn't listed for media duties by the PGA of America so we didn't get too much of an insight into Lefty's thoughts and feelings. 

Although at this point, it's pretty clear where the 52-year-old stands on all things LIV, PGA Tour and the landscape of men's professional golf.

After turning in rounds of 73, 72, 75 and 70, Mickelson was crowded by a few reporters who wanted to get some reaction. 

That reaction? He will continue to hold the PGA Tour, others 'accountable' as apparently he 'knows things that others don't'. 

The question was why he continues to get involved in all the mud-slinging online. 

His online activity has seen him accuse the Official World Golf Ranking of colluding against LIV Golf. He has also claimed PGA Tour boss Jay Monahan rejected his efforts to bring $1bn for eight elevated events. 

Mickelson told Barstool Sports' Dan Rapaport: 

It's important to note that Mickelson may well have some credible ammo. 

His comments after competing in the second major of 2023 came after it was confirmed Mickelson, Bryson DeChambeau and Sergio Garcia met with investigators with the U.S. Department of Justice. 

The federal department opened an inquiry into the PGA Tour's alleged antitrust behaviour last year. The PGA of America, Augusta National, Official World Golf Ranking, R&A and USGA are also included in this investigation. 

The New York Times reported that DOJ investigators met with the LIV Golf players before the PGA Championship got underway. 

Mickelson reportedly refused to confirm what he discussed with DOJ investigators.
