AILSA CHANG, HOST: All right, New York Knicks fans have never been short on belief. Their team has not won the NBA championship in more than 50 years. That's a half century, people. But now the Knicks have won 13 straight games and are just two wins away from the title. And tonight, the NBA Finals head to New York City for Game 3 against the San Antonio Spurs. And President Trump is expected to show up in person, which means a whole lot of security around Madison Square Garden.
