Tucker Carlson grilled Ted Cruz about Iran, telling the Texas Republican at one point that he doesn't "know anything" about the country.

In an interview that highlighted a rift on the far right over the role of the United States in confronting Iran, the host confronted the senator over his hawkish stance, suggesting he was ill-informed.

The interview kicked off with Cruz claiming Iran needed an uprising before a question about Iran's demographics sent the whole convo straight off a cliff.
