Blumenthal, the chair of a Homeland Security investigative subcommittee, launched a probe into the controversial deal on Monday, demanding leaders submit scores of records related to the merger June 26.

“While few details about the agreement are known, PIF’s role as an arm of the Saudi government, and PGA Tour’s sudden and drastic reversal of position concerning LIV Golf raise serious questions regarding the reasons for and terms behind the announced agreement,” the Connecticut Democrat wrote in a letter to PGA Commissioner Jay Monahan.

Should the leaders behind the deal ignore his request, “any of the tools at our disposal, including subpoenas and hearings, recommendations for action and legislation are all on the table,” Blumenthal said.

“We are ready and willing to seek information by whatever legal means we have to obtain it.”
