Tucker Carlson welcomed “Fight for $15” activist Kendall Fells to his show Monday night to discuss the joining of the minimum wage group and a Black Lives Matter group to protest a variety of issues.

Carlson began by saying he’s not opposed to raising the minimum wage, but is confused by Fells’ immigration stance. Fells argues that we need more workers in the country because it saves on labor — but the host pointed to a study that showed low-skilled legal and illegal immigration lowered wages for American workers by about $402 billion per year.

Watch the two battle it out over Fells’ conflicting stance on minimum wage increase and immigration.
