President Donald Trump is reportedly set to take a lap of honour around the street circuit hosting the Freedom 250 Grand Prix, according to a new report. The race, run by the NTT IndyCar Series, is being held on a temporary street course through Washington, DC, and is being billed as one of the biggest events on this year's IndyCar calendar.

Drivers including Josef Newgarden and Kyle Kirkwood have described the race as a "once-in-a-lifetime" event, given its unusual setting among the US capital's landmarks. The report of Trump's involvement adds a high-profile political dimension to what organisers are already promoting as a showcase event for the sport, though further details of his participation have not yet been confirmed.
