President Donald Trump is threatening to relocate World Cup matches set to be played next year in suburban Boston. He suggested Tuesday that parts of the city had been “taken over” by unrest. The city is set to stage seven matches as the U.S. cohosts the 2026 World Cup with Mexico and Canada. It wasn’t immediately clear what unrest Trump was referring to, but earlier this month there were multiple arrests in connection with a pro-Palestinian protest that turned violent on Boston Common. World Cup host sites aren’t up to Trump but are contracted with FIFA, which would face significant logistical and legal issues if it made changes now.
