Funding for the new purpose-built facility in Austin, Texas, home to the United States Grand Prix from 2012, looks in doubt.
It was revealed that a government subsidy to the tune of $25 million (£15.5m) is under threat after the Senate Finance Committee admitted it could be better spent elsewhere.
“At a time when people are stressed about their schools, stressed about their jobs, stressed about health care and nursing homes, for us to check off 25 million for race cars – I think we make people say where are their priorities,” senator Dan Patrick told KXAN.
“That 25 million would pay for 500 teacher salaries – how can we explain to people we’re spending that money on race cars?”
The funding might still be restored however.
