A day earlier, Omar described death threats she announced she had got in response.
"People truly don't understand the scale, intensity, & volume of threats targeting @IlhanMN," tweeted Ocasio-Cortez, a fellow member of the so-called "Squad" of progressive Democrats.
"Kevin McCarthy is so desperate to be speaker that he is working with his Ku Klux Klan caucus to look aside & allow violent targeting of [women of color] members of Congress. This cannot be ignored."
"While people toss out clichés like 'we condemn all forms of racism & bigotry,' the fact is Islamophobia is far too often tolerated and ignored."
"Bigotry is not made unacceptable by what one says about it, it's made acceptable based on whether there are consequences for it or not."
Ocasio-Cortez went on to say that the GOP had been granted "freedom to incite" without fear of consequences, mainly when the victims were from minority communities.
Last week, McCarthy angered Democrats and some in his party by pledging to restore committee assignments to two lawmakers blamed for encouraging violence against lawmakers.
The latest controversy erupted with a video revealing Boebert addressing followers throughout the Thanksgiving break when she told a story about sharing an elevator with Omar.
'"Well, she doesn't have a backpack. We should be fine,'" Boebert recalled speaking to an aide, to hoots of laughter.
"And I said, 'Oh look, the jihad squad decided to show up for work today.'"
Omar explained that the incident never even happened. And the comments quickly attracted widespread criticism and calls for punishment.
Boebert tweeted on Thursday: "I apologize to anyone in the Muslim community I offended with my comment about Rep Omar. I have reached out to her office to speak with her directly."
"There are plenty of policy differences to focus on without unnecessary distraction."
Since then, an additional video dating back to September revealed Boebert making a similar joke.
She called Omar to smooth things over, though their conversation ended when the Democrat hung up the phone with each lawmaker demanding an apology.
"She didn't want to hear what I had to say," Boebert told Laura Ingraham on Fox News on Tuesday evening.
"Omar and the left don't want an apology. They want public humiliation. They want to cancel me but that's not going to happen… I will not be canceled."
Recent precedent suggests she can count on the support of McCarthy in the face of Democratic criticism.
