AUSTIN, Texas -- Two of Formula One's three races in North America are facing financial issues that are raising concerns about their future.
Organizers of the U.S. Grand Prix won't be reimbursed at least $20 million from the state of Texas for the 2018 race after missing a paperwork deadline set by law. And new questions lurk about the future of the Mexican Grand Prix after the country's new president suggested the government may not spend on the race like it has the last four years.
Both races have been popular with drivers and fans, and enjoy key dates on the F1 calendar.
