In February 2019, Loomer traveled to Minnesota with Jacob Wohl, a right-wing perpetrator of Internet fraud, and Ali Alexander, a far-right activist. The group said they were "investigating" whether Omar had married her brother so that he could obtain U.S. citizenship, a baseless rumor that had circulated in Minnesota politics since 2016. Wohl, Loomer, and Alexander were unable to find any immigration irregularities by Omar. A few weeks later, in March 2019, Wohl and Loomer were ejected from the 2019 CPAC when they attempted to present evidence from their trip to Minnesota. Loomer had previously accosted Omar with the same unsubstantiated allegations at the August 2018 Omar campaign event, the one attended by Tlaib. In 2019, Loomer uploaded a video to Instagram about Omar, blaming her and all Muslims for the September 11 attacks and asserting that "Muslims should not even be allowed to seek positions of political office in this country."
