Jeb, who lives in Coral Gables, is the brother of George W. Bush, who was a co-owner of the Texas Rangers from 1989-94.
Reports emerged in February that Marlins owner Jeffrey Loria is a candidate to serve as President Trump's ambassador to France.
Forbes has previously valued the team at $940 million, good for 25th out of 30 teams. His older brother, former USA president George W. Bush, was part-owner of the Texas Rangers from 1989-98.
Both Jeter and Bush have homes in Florida.
The Associated Press is citing a person familiar with the partnership.
Jeter has expressed interest in owning an Major League Baseball team for years - and has even gotten the blessing of the Steinbrenner family.
Loria is now seeking a suitor to buy his franchise. "In my mind he'll always be a Yankee", Girardi said.
