9/11 Org. 'Deeply Offended' By PGA Tour, LIV Golf Merger

A prominent 9/11 memorial organization is teeing off on the PGA's decision to join forces with the Saudi-backed LIV Golf tour ... saying the move is nothing but an act of betrayal.

9/11 Families United -- a group of thousands of family members whose loved ones were killed or impacted during the September 11, 2001 terrorist attacks -- tells TMZ Sports it is "shocked and deeply offended" by Tuesday's news of the PGA/LIV merger.

"PGA Commissioner Jay Monahan co-opted the 9/11 community last year in the PGA's unequivocal agreement that the Saudi LIV project was nothing more than sportswashing of Saudi Arabia's reputation," chairman Terry Strada, whose husband died in the World Trade Center's North Tower, said in a statement.

"But now the PGA and Monahan appear to have become just more paid Saudi shills, taking billions of dollars to cleanse the Saudi reputation so that Americans and the world will forget how the Kingdom spent their billions of dollars before 9/11 to fund terrorism, spread their vitriolic hatred of Americans, and finance al Qaeda and the murder of our loved ones."

Of course, the 9/11 hijackers had strong ties to Saudi Arabia. Fifteen of the nineteen men who carried out the attack were citizens of the Middle Eastern country. Al Qaeda leader Osama bin Laden was also born in Saudi Arabia in 1957.

Despite the hijackers largely coming from Saudi Arabia, the country has always denied playing any role in the terrorist attack that killed nearly 3,000 people. The FBI and CIA have also stated Saudi Arabia was not behind the attacks.

"Make no mistake – we will never forget," Strada added.

Monahan is well aware of the backlash directed at players who jumped to LIV last year -- he was previously asked about 9/11 Families United calling it an act of betrayal at the time ... and he felt it was necessary for those athletes to apologize to those affected by the terrorist attacks.

It's safe to say the 9/11 org. no longer feels his words were sincere.

"Mr. Monahan talked last summer about knowing people who lost loved ones on 9/11, then wondered aloud on national television whether LIV Golfers ever had to apologize for being a member of the PGA Tour. They do now -- as does he. PGA Tour leaders should be ashamed of their hypocrisy and greed."

"Our entire 9/11 community has been betrayed by Commissioner Monahan and the PGA as it appears their concern for our loved ones was merely window-dressing in their quest for money – it was never to honor the great game of golf."
