Denver, Colorado - A transgender pilot filed a defamation lawsuit Wednesday against a rightwing influencer who falsely claimed on social media that she was flying a military helicopter that collided with a passenger jet in Washington in late January.

Jo Ellis sued Matt Wallace, an influencer with 2.2 million followers on the platform X, saying he "concocted a destructive and irresponsible defamation campaign" against her following the crash that killed 67 people aboard both aircrafts, according to the lawsuit filed in the US district court in Colorado.

One of Wallace's posts, which garnered millions of views, claimed the Black Hawk pilot might have participated in a "trans terror attack," falsely accusing Ellis of intentionally causing the mid-air collision due to her "depression" and "gender dysphoria," according to the lawsuit.

There was no immediate comment from Wallace, who later deleted his posts about Ellis.

The suit further accused Wallace of using his prominent stature on X, where he maintains multiple accounts, of seeking to "monetize a false narrative."

As tens of thousands of social media posts falsely accused Ellis of piloting the ill-fated helicopter, she worried that someone might track down her home using public records.

She told AFP in an interview in February that she was forced to temporarily move her family to a new location and arrange for private armed security.

The damage caused by Wallace was "instantaneous and immense," resulting in suffering for her family due to the hate inspired by his "lies," the lawsuit said.

Ellis eventually posted a "proof of life" video on Facebook, which quelled only some of the rumors.

The threats facing Ellis, who has served in the National Guard since 2009 and has deployed to Iraq and Kuwait, highlight the real-life impact of disinformation for transgender people at a time when there has been a sharp uptick in political attacks.

President Trump has signed several executive orders targeting the transgender community, including one instructing the government to recognize only two sexes, male and female.

In the aftermath of the crash, Trump had suggested – without offering any evidence – that the aviation authority's diversity hiring practices could partly be to blame for it, making trans people a ripe target for baseless online rumors.

Ellis' lawsuit is part of a trend that has seen defamation lawsuits increasingly becoming a tool used by US citizens and pro-democracy groups to hold misinformation spreaders financially and personally accountable.
