TV personality and capitalist Mark Cuban appeared on “Tucker Carlson Tonight” Tuesday and tussled with the show’s host over President Trump’s H-1B executive order that could curb the number of foreign workers in America.

Cuban argues that H-1B visas allow companies to shop for the best talent, saying “either you believe in capitalism…or you don’t.” This is when Carlson laughed and retorted “I love that. When did the left become addicted to market fundamentalism? There are many in-betweens!”

This is when Cuban got frustrated, saying he is “not the Left by a longshot.” Watch the clip above.
