[17][18] In March 2015, Loomer used a concealed video camera to record her conversations with Barry University officials, discussing the idea of starting a club called "Sympathetic Students in Support of the Islamic State of Iraq and Syria".

[21] Shortly thereafter, the university suspended Loomer for violating the student code of conduct and a professor shown in the video filed criminal charges against her for recording him without his knowledge.

[24] On November 8, 2016, the day of the 2016 U.S. presidential election, Loomer, as part of a Project Veritas stunt, went to a polling station dressed in a burqa and asked for a ballot under the name of Huma Abedin.

[20] On June 10, 2017, she gave a speech to a crowd of "anti-Sharia" marchers in New York City organized by ACT for America and condemned "liberals who aligned themselves with Sharia law".

[20] Her first stunt for Rebel Media was on June 16, 2017, when she disrupted a Shakespeare in the Park presentation of Julius Caesar in New York City, by walking on stage during the live performance shortly after the title character was assassinated.

[30][31] Earlier in the week, performances of the play had elicited criticism for depicting women and minorities perpetrating the violent assassination of Trump as U.S.

[33] On June 19, Alyssa Rosenberg of The Washington Post wrote that she did not believe Loomer was genuinely offended by the play, but was looking for attention and to collect a US$1,000 bounty that alt-right social media personality Mike Cernovich had offered to anyone who disrupted the production.

[34] Appearing on the Fox News program Hannity a few days after her arrest, Loomer said she knew that disrupting the play would result in criminal charges against her.

During the interview, she objected to the depiction of Caesar in the play and accused the left of "systematically and programmatically" using "free expression as a pretext to incite violence".

[29][35] A "Free Laura" website, soliciting donations for her arrest, had been purchased by Loomer's employer, Rebel Media owner Ezra Levant, six hours before the play started.

They wore Mexican serapes and sombreros, with one wearing a large false mustache, and said they were protesting Governor Gavin Newsom's stance on immigration.

Marjorie Taylor Greene, a far-right member of the United States House of Representatives, condemned this remark as "appalling and extremely racist".

[65] She claimed the Federal Bureau of Investigation suspected a terrorist attack and that there may be a "Jihad plot" at the Macy's Thanksgiving Day Parade, despite the vehicle traveling on the U.S. side of the border towards Canada.

[67] In 2023 and 2024, Loomer falsely attributed social media posts to family members of judges Arthur Engoron and Juan Merchan, who were overseeing court cases involving Donald Trump.

[71] Loomer lost the 2020 United States House of Representatives election in Florida's 21st congressional district to incumbent Democrat Lois Frankel.

[74] The White House later downplayed Trump's support for Loomer and for Congressional candidate Marjorie Taylor Greene, saying, "The president routinely congratulates people who officially get the Republican nomination for Congress, so he does that as a matter of course ...

[82][83] Backed by the group American Liberty Fund, Loomer was endorsed by Representatives Marjorie Taylor Greene and Paul Gosar,[84] as well as Roger Stone and Michael Flynn.

[5][92] In response, she said that "left wing terrorists and tech tyrants" were "trying to shut [her] down" and that she would "stop at nothing to make sure justice is served for the way Silicon Valley has disenfranchised me, falsely accusing me of being a white supremacist, a Nazi, anti-Muslim, a racist, a bigot, and every other smear in the book.

[95] Loomer used press credentials to attend the March 2018 trial of Noor Salman, the wife of the perpetrator of the June 2016 Orlando nightclub shooting.

Shouting from the visitor gallery, she accused Twitter CEO Jack Dorsey, who was testifying before the committee, of censoring conservatives on the platform and of attempting to influence elections in favor of Democrats.

[96] Republican representative Billy Long began a mock auction chant, pretending he was selling Loomer's mobile phone, until she was escorted out.

[73] Loomer was banned from the 2019 Conservative Political Action Conference (CPAC) after aggressively confronting reporters, using her press credentials to follow them into a media-only area after they had declined to speak with her.

The Minneapolis Star Tribune reported that the "video of the incident includes audio of Loomer asking Tlaib if she was 'willing to admit ... that Hamas is a terrorist organization.

[114] Loomer has denounced the alt-right and publicly repudiated white supremacist Richard B. Spencer, who coined the term, and refused to share a stage with him.

[117] Donald Trump, who The New York Times reported wanted to hire Loomer for a campaign role, has described her as "very opinionated", while U.S. representative Marjorie Taylor Greene has claimed she is "mentally unstable and a documented liar".

[g] On November 1, 2017, the day after a terrorist attack in New York City, Loomer tweeted that she was late to a conference because she could not find a "non Muslim cab or @Uber @lyft driver".

[128] In February 2019, Loomer traveled to Minnesota with Jacob Wohl, a right-wing perpetrator of Internet fraud,[129][130] and Ali Alexander, a far-right activist.

"[125] Right Wing Watch reported in February 2019 that donations solicited by Loomer were going to the address of The United West, an organization the Southern Poverty Law Center lists as an anti-Muslim hate group.

"[152] Loomer downplayed the severity of COVID-19, writing in December 2020, "I hope I get COVID just so I can prove to people I've had bouts of food poisoning that are more serious and life-threatening than a hyped-up virus".

[157] Loomer referred to African-American Democratic elected officials Kamala Harris, Fani Willis, and Letitia James as "DEI Shaniquas".
