Washington DC – A battle erupted on Wednesday between Democratic Congresswoman Marie Newman and the highly controversial pro-Trump Representative Marjorie Taylor Greene on the subject of LGBTQ rights.

Marie Newman of Illinois and Republican Representative Marjorie Taylor Greene of Georgia are at odds on the subject of transgender rights.

According to the Chicago Tribune, the flare-up began on the House floor on Tuesday when members of Congress spoke for and against the Equality Act, which aims to prohibit discrimination based on gender identity and sexual orientation.

Newman gave a speech in favor of the act, while Taylor Greene spoke in opposition.

Afterwards, Newman shared a video of herself on Twitter placing a transgender rights flag outside her office door. "Our neighbor, @RepMTG, tried to block the Equality Act because she believes prohibiting discrimination against trans Americans is 'disgusting, immoral, and evil.' Thought we’d put up our Transgender flag so she can look at it every time she opens her door," the congresswoman said with a wink-emoji.

But Marjorie Taylor Greene didn't take that lying down, retaliating with her own post: "Our neighbor, @RepMarieNewman, wants to pass the so-called 'Equality' Act to destroy women’s rights and religious freedoms," Taylor Greene wrote above the video of herself hanging a sign in the hallway reading, "There are TWO genders: MALE & FEMALE 'Trust The Science!'"

"Thought we’d put up ours so she can look at it every time she opens her door," Taylor Greene added. The move is particularly offensive as Newman has a daughter who is transgender.

Taylor Greene also got personal in her attack, tweeting above a video of Newman's floor speech: "As mothers, we all love and support our children. But your biological son does NOT belong in my daughters’ bathrooms, locker rooms, and sports teams."

Marie Newman is a Chicago native who, among other things, established a national non-profit to help stop bullying based on her own child's negative experiences.

Taylor Greene, on the other hand, is a freshman congresswoman known for her inflammatory statements and support for QAnon and other conspiracy theories. The list includes suggesting 9/11 was a hoax, claiming the Parkland shooting survivors faked the incident, and supporting the execution of Democratic politicians.

Last but not least, she even suggested that a Jewish family was responsible for the California wildfires by shooting laser beams from space.
