Fox News host Tucker Carlson said Tuesday that Rep. Ilhan Omar (D-Minn.) has "spent the rest of her life attacking" the U.S. after immigrating to the country from Somalia.

Carlson's comments came as part of a discussion of a 2017 tweet from Omar highlighting the number of Somalis killed by U.S. forces in a 1993 battle in Mogadishu. The fight was dramatized in the film "Black Hawk Down."

"Here's someone who was brought to the United States at public expense simply because we're a kind country that accepts a lot of refugees," Carlson said as he interviewed Kyle Lame, a retired sergeant major who fought in Mogadishu.

"And rather than being grateful for that, she's spent the rest of her life attacking this country. Why?"

The remarks are just the latest criticism from Carlson toward Omar, who has become a huge target for the right. Omar is one of the first two Muslim women elected to Congress, and has stirred controversy with comments about Israel some have viewed as anti-Semitic.

She has sought to highlight the discrimination and prejudice faced by Muslims, and also came under criticism earlier this year from conservatives for remarks about the Sept. 11 attacks - including from President Trump.

In the 2017 tweet about Mogadishu, Omar wrote that "thousands of Somalis" had been killed in response to another tweet that referred to the battle as the "worst terrorist attack in Somalia history."

"In his selective memory, he forgets to also mention the thousands of Somalis killed by the American forces that day!" Omar wrote, adding the hashtag #NotTodaySatan.

NPR reported in 2013 that it is unclear how many Somali casualties occurred during the battle, noting "hundreds, perhaps thousands of Somalis were killed."

Eighteen American soldiers died in the fighting and dozens more were wounded after two Black Hawk helicopters were shot down flying into Mogadishu on a mission against Somali militiamen.

The bodies of several U.S. soldiers were dragged through the streets, and the entire episode was a black eye for President Clinton's new administration, which withdrew much of its involvement in the region.

Omar fled violence in Somalia as a child and spent four years in a Kenyan refugee camp before entering the United States in 1992 - before the Mogadishu battle took place.
