Rep. Ilhan Omar of Minnesota faced criticism this week after a video emerged of a remark she made in a speech to the Council on American-Islamic Relations late last month.

"CAIR was founded after 9/11 because they recognized that some people did something and that all of us were starting to lose access to our civil liberties," Omar said.

Critics quickly jumped on Omar's statement, accusing her of trivializing the 9/11 terrorist attacks.

The New York Post on Thursday criticized Omar's controversial remark about the 9/11 attacks by covering its front page with her quote and an image of the World Trade Center's twin towers collapsing.

Several prominent Democrats accused the conservative tabloid of bigotry and inciting violence against the Muslim congresswoman, who has increasingly become the target of death threats.

"The NY Post knows exactly what it's doing — taking quotes out of context and evoking painful imagery to spread hate and endangering the life of Rep. Omar," Rep. Rashida Tlaib tweeted.

Rep. Ilhan Omar, a Minnesota Democrat, faced criticism this week after a video emerged of a remark she made in a speech to the Council on American-Islamic Relations late last month.

"For far too long we have lived with the discomfort of being a second-class citizen, and frankly I'm tired of it, and every single Muslim in this country should be tired of it," Omar said. "CAIR was founded after 9/11 because they recognized that some people did something and that all of us were starting to lose access to our civil liberties."

CAIR was founded in 1994. Omar's spokesman, Jeremy Slevin, reportedly said the congresswoman misspoke.

But critics quickly jumped on Omar's statement, accusing her of trivializing the 9/11 attacks. And on Thursday, the New York Post criticized Omar's controversial remark by covering its front page with an image of the World Trade Center's twin towers collapsing.

Some Democratic lawmakers slammed the conservative tabloid on Twitter. Rep. Alexandria Ocasio-Cortez of New York called it a "horrifying, hateful cover."

"The NY Post knows exactly what it's doing — taking quotes out of context and evoking painful imagery to spread hate and endangering the life of Rep. Omar," Rep. Rashida Tlaib tweeted.

A spokesperson for The New York Post said the paper has no comment on the criticism.

Days earlier, a New York man was arrested and charged with threatening to assault and kill Omar, the US Attorney's Office for the Western District of New York said.

On Wednesday, the "Fox & Friends" host Brian Kilmeade questioned whether Omar is loyal to America. He later clarified his comment, saying he "didn't intend to question whether Rep. Omar is an American" but was "questioning how any American, let alone a United States Congresswoman, could downplay the 9/11 attacks."

Omar defended herself against accusations that she's isn't a loyal American.

"I took an oath to the Constitution. I am as American as everyone else is," Omar said on "The Late Show with Stephen Colbert" on Wednesday.
