A poster connecting Minnesota Rep. Ilhan Omar to the Sept. 11 terror attacks sparked a chaotic scene at the West Virginia statehouse on Friday, where lawmakers got into heated arguments and one staffer was injured, a report said.

The poster showing the Democratic congresswoman next to the Twin Towers exploding into flames was part of a display for “WV GOP Day,” according to WVNews.

“’Never forget’ —you said….” read the caption of the image with Omar, a Muslim, in her hijab. “I am the proof — you have forgotten.”

Omar is a Somalian refugee and one of the first two Muslim women sworn into Congress this year.

Several Democratic lawmakers condemned the sign, with one delegate calling it ”ugly and “hateful.”

Republicans argued that the poster was a “freedom of speech” issue.

The House’s sergeant-at-arms, Anne Lieberman, was allegedly overheard saying “all Muslims are terrorists,” and resigned over the incident.

During fierce debate in the Capitol rotunda, lawmakers nearly came to blows as one staffer was injured. It was not clear how seriously.

Omar responded to the incident on Twitter by writing, “No wonder why I am on the ‘Hitlist’ of a domestic terrorist and ‘Assassinate Ilhan Omar’ is written on my local gas stations.”

She added: “Look no further, the GOP’s anti-Muslim display likening me to a terrorist rocks in state capitols and no one is condemning them!”
