Tucker Carlson on Wednesday had a tense exchange with Jorge Ramos on the issues of immigration and race, which culminated with the Fox News host declaring that the Mexican-born Univision anchor was whiter than him.

Ramos, who is a senior anchor at the Spanish-language network, appeared on the program Tucker Carlson Tonight to talk about his stance on President Donald Trump's immigration policies.

Carlson began by introducing his Univision counterpart as one of President Trump's 'loudest critics on immigration' and then asked Ramos to clarify his recent comments about the United States being 'our country, not theirs.'

Surprising comment: At one point, Carlos snapped at Ramos, saying, 'Let me just point out that you are white, obviously; you're whiter than I am: you have blue eyes'

‘Who is the “us,” and who is the “they?”’ Carlson demanded of his guest.

Speaking from Univision's Miami studios, Ramos explained that there are people in the country who want to go back to 1965, when there was a white majority, and who believe that Latinos, immigrants and refugees have no place here.

'This is not a white country. This is not their country. It is ours,' Ramos said before adding, 'this is a multiracial country and we must be tolerant.'

Carlson then snapped at Ramos: 'Let me just point out that you are white, obviously. You're whiter than I am: you have blue eyes, so I don't know exactly what you mean by "white" or "Latino."'

Ramos, a journalist and author widely regarded as the 'Walter Cronkite of Latin America,' was born in Mexico City in 1958 and came to the US in 1983 on a student visa.

He has been co-hosting the nightly Spanish language newscast Noticiero Univision since 1986, winning eight Emmy Awards in the process.

Since taking over Megyn Kelly's former 9pm slot in the Fox News lineup two months ago, Carlson, 47, has been raking in big ratings for the network

In the course of Wednesday night's tense on-air clash, a seemingly befuddled Carlson pressed Ramos to explain the term 'Latino,' arguing that various groups that traditionally fall under that category, inclduing Afro-Cubans, German Guatemalans, non-Spanish-speaking Peruvians and 'blue-eyed rich Mexicans like you,' seem to have little in common and don't even like each other.

Ramos replied that Latinos, or Hispanics, are people who come from the region of Latin America and tend to speaks Spanish, but that answer failed to satisfy Carlson.

'It still doesn't make any sense to me at all. But as a political matter it makes a lot of sense because it allows people like you to say, "I represent everybody on an entire continent."' he said.

Since taking over Megyn Kelly's former 9pm slot in the Fox News lineup two months ago, Carlson, 47, has been raking in big ratings for the network.

Nielsen data reported that on March 2, Carlson had the fourth-highest ratings in all of television, according to WesternJournalism.com.
