If the phone call was supposed to smooth over an ugly row, the Colorado Republican's video message would just inflame the matters.
And it will build pressure on Republican leaders to condemn her comments and punish her behavior.
According to Boebert's account, the two demanded apologies from each other in their phone call.
"She continued to press and I continued to press back and then representative Omar hung up on me."
"Rejecting an apology and hanging up on someone is part of cancel culture 101."
It comes after Boebert was captured on video making an Islamophobic joke of sharing an elevator with Omar.
"Well, she doesn't have a backpack. We should be fine," Boebert recalled while addressing supporters during the holiday break.
"And I said, 'Oh look, the jihad squad decided to show up for work today."'
Her remarks attracted widespread criticism and call for punishment.
For her part, Omar announced she had received the call because she believed in engaging those with whom she disagreed.
"Instead of apologizing for her Islamophobic comments and fabricated lies, Rep. Boebert refused to publicly acknowledge her hurtful and dangerous comments," she announced in a statement.
"She instead doubled down on her rhetoric and I decided to end the unproductive call."
"I believe in engaging with those we disagree with respectfully, but not when that disagreement is rooted in outright bigotry and hate."
The video triggered an angry reaction last week, while lawmakers were home for Thanksgiving.
"Saying I am a suicide bomber is no laughing matter," Omar tweeted Friday. "[GOP Leader Kevin McCarthy] and [Speaker of the House Nancy Pelosi] need to take appropriate action, normalizing this bigotry not only endangers my life but the lives of all Muslims. Anti-Muslim bigotry has no place in Congress."
The Congressional Black Caucus issued a rebuke of Boebert Friday, announcing her conduct was "morally reprehensible and dangerous" and would lead to further death threats on Omar's family.
Boebert tweeted 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."
