Omar, the freshman Democratic congresswoman from Minnesota who came to the U.S.as a child seeking asylum from Somalia, responded by calling Carlson "a racist fool, " his show "a nightly platform to white supremacist rhetoric" and said "advertisers should not be underwriting hate speech".
Carlson said there are "serious reasons to wonder about her judgment and her competence".
Omar railed against some of Carlson's comments via Twitter both Tuesday night and Wednesday.
Donald Trump showed his support for Carlson via retweet.
Carlson also offered comments supportive of immigrants and Omar's rise to Congress.
On Tuesday, Carlson said USA immigration laws are "dangerous" because they let people like Omar, who he said "hates" America, into the country.
After recounting Rep. Omar's perilous journey to the United States as a Somali immigrant and how her family was successfully granted asylum, Carlson said: "Ilhan Omar has a lot to be grateful for, but she isn't not at all".
After recounting his remarks the night before, Carlson declared it wasn't about race and accused Omar of using race to get what she wants.
"She might have had a prior [arrest],' Omar said of the woman in the story when the similarities were pointed out".
The Washington Post reported that Omar recently told 400 Richfield High School students that she was sent to the courts to report on problems for a Minneapolis city councilman five years ago. In some ways, the real villain in the Ilhan Omar story isn't Omar, and it is a group of our fellow Americans. Omar went on to urge her followers to boycott his show's advertisers. As we have noted many times, however, she is a bottomless fount of grievances and complaints. They just try to silence us. The irony there is that if she wasn't a member of Congress, she'd be a member of the KKK. "They are direct attacks on American Jews, a minority community in the United States. African American lady" who had to spend a weekend in jail after stealing a $2 loaf of bread to feed her "starving 5-year-old granddaughter". She has undisguised contempt for the United States and its people.
Along with documenting her illegal filing of tax returns with a man who was not her legal husband, the new documents obtained by the Star Tribune reveal the Omar campaign's efforts in 2018 to keep the story of her marriage to Elmi out of the media. That is exactly what she is doing. "Omar has made a career by denouncing anyone or anything in her way as racist, that would include virtually all of her political and personal opponents".
