Nikita Mazepin took a swipe at Haas chief Guenther Steiner as he vowed he would never accept an invitation to work with the team again.
Mazepin spent one year with the team, and was due to continue racing into this season. But, following the Russian invasion of Ukraine earlier this year, he was axed with just a few weeks to go before the start of the season.
Drivers from Russia are allowed to continue competing under FIA rules. But they must do so under a neutral flag, or represent another country for which they are eligible to compete, and agree not to support the Russian invasion in public.
