“We need strong conservative Christians to take action against these socialists who want to tear our country apart,” was the headline of her contribution.
As of Friday noon, Facebook removed the photo and said it was against the guidelines of the social network.
The Georgia Republican, with the backing of President Donald Trump, previously subscribed to the QAnon conspiracy theory and has a history of Islamophobic and bigoted comments on social media. Greene is ready to be elected to Congress this fall after winning the Republican primary in a solid Republican district in Georgia.
Earlier on Friday, Omar, who is a Muslim with Tlaib, said the now deleted photo of Greene was “incitement”
; and called on Facebook to remove the “violent provocation”.
“Posting a photo with an assault rifle next to the faces of three women of color is not advertising. It’s incitement,” the Minnesota Democrat posted on Twitter. “There have been death threats in response to this post. Facebook should remove this violent provocation.”
Greene’s campaign told CNN in an emailed statement that those who believe the image to be violent are “paranoid and ridiculous”.
CNN reached out to the campaign on Friday afternoon after Facebook removed the image.
Greene, who is running for Georgia’s 14th congressional district, has stood up to the three progressive Democratic women in Congress who, along with Rep. Ayanna Pressley, refer to themselves as the “Squad”.
“Leftists out of hatred of America want to tear this country down,” wrote Greene in her Facebook post, which was her second post addressed to Congress women in recent days. “Politicians have failed this country. I’m tired of seeing weak establishment Republicans playing defense. Our country is at stake. America needs fighters who tell the truth.”
Last year, the four Democratic women in Congress – Ocasio-Cortez, Omar, Pressley, and Tlaib – were the target of a controversial billboard in North Carolina for a gun deal. The sign was deemed violent and removed.
Politico reported that Greene had previously posted on social media that Muslims do not belong to the government and that, among other things, there is “an Islamic invasion of our government offices”.
CNN’s KFile reported that Greene wrote two conspiratorial blog posts speculating that the 2017 white nationalist rally in Charlottesville, Virginia that resulted in the death of a counter-protester was an “inside job” and the conspiracy theory debunked “Pizzagate” promoted which some Democratic leaders claim are trafficking and pedophilia rings as real.
Greene told Fox News last month after her first win that while reading and discussing QAnon topics, she decided to “take another route” after encountering “misinformation”.
This story has been updated to reflect that Facebook removed the photo.
