The two leaders wagered British and American beer on the outcome. But the game ended in a 1-1 tie, leaving the payout unclear.
Obama, during a telephone call with Cameron on Saturday, claimed history was on the U.S. side. In 1950, the Americans stunned mighty England 1-0 in the only prior World Cup meeting between the two national teams.
While the bet was the best English lager against the best all-around U.S. beer, the White House declined to say what brands the president and prime minister had in mind.
