Federal prosecutors investigating former President Donald Trump’s handling of classified documents have subpoenaed his family business for records related to his dealings with LIV Golf, according to a report. 

The fledgling Saudi-backed golf tour plans to hold tournaments this year at three properties owned by Trump. 

The previously unreported subpoenas were issued to the Trump Organization by prosecutors working for special counsel Jack Smith, who is overseeing multiple federal criminal investigations into the 76-year-old former president, the New York Times reported on Thursday.

It’s unclear why prosecutors are interested in Trump’s ties to LIV Golf and how the subpoenas fit into the scope of Smith’s investigation into how classified records from Trump’s days in the White House wound up at the ex-commander-in-chief’s Mar-a-Lago estate. 

The subpoenas related to the LIV Golf are part of a flurry of activity from Smith’s team in the classified documents probe, according to the report. 

Prosecutors have reportedly obtained the confidential cooperation of a Mar-a-Lago insider who has provided investigators with a picture of the storage room at Trump’s Palm Beach, Fla., estate where classified material may have been held.
