WASHINGTON—The chairman of a Senate investigations subcommittee issued a subpoena Wednesday for documents on Saudi Arabia’s new golf partnership with the PGA Tour, saying the kingdom had to be more transparent about what he said was its $35 billion in investments in the United States.
The move is the latest to challenge Saudi Arabia’s assertion that as a foreign government that enjoys sovereign immunity from many U.S. laws, it is not obliged to provide information on the golf deal.
