Court documents reveal that Nikita Casap’s alleged manifesto calling for Trump’s assassination cited multiple Terrorgram publications and urged people to read the writings of a network member who murdered two people outside an LGTBQ+ bar in 2022.

A Wisconsin teenager accused of murdering two family members and plotting to assassinate President Donald Trump was inspired by Terrorgram, a white supremacist network that operated on the Telegram messaging and social media platform for half a decade, according to federal court records.

The Terrorgram community, which has been linked to around three dozen criminal cases around the globe, including at least three mass shootings, was profiled last month in stories and a documentary produced by ProPublica and FRONTLINE.

The court documents allege that Nikita Casap, a 17-year-old from Waukesha, Wisconsin, wrote a three-page manifesto calling for the assassination of Trump in order to “foment a political revolution in the United States and ‘save the white race’ from ‘Jewish controlled politicians.’”

In his manifesto, Casap allegedly encouraged people to read the writings of Juraj Krajčík, a longtime Terrogram figure who murdered two people in an attack on an LGBTQ+ bar in Bratislava, Slovakia, in 2022, according to the court records. Casap also allegedly recommended two publications produced by the Terrorgram Collective, a secretive group that produced alleged hit lists, videos and written publications — including instructions for building bombs and sabotaging critical infrastructure — and distributed them throughout the Terrorgram ecosystem.

Launched in 2019, Terrorgram was a constellation of scores of Telegram channels and chat groups focused on inciting acts of white supremacist terrorism and anti-government sabotage. At the network’s peak, some Terrorgram channels drew thousands of followers. Over the past six months, however, the network has been disrupted as authorities in Canada, the U.S. and Europe have arrested key Terrorgram influencers and community members.

But the violence hasn’t stopped.

Casap in February allegedly shot and killed his mother, Tatiana Casap, and stepfather, Donald Mayer; stole their property; and fled in their Volkswagen Atlas, Waukesha County prosecutors say. He was arrested in Kansas. Prosecutors have charged the teen with two counts of first-degree homicide, as well as identity theft and other theft charges. He is expected to be arraigned on May 7, according to court records.

A witness told local investigators that Casap “was in touch with a male in Russia through the Telegram app and they were planning to overthrow the U.S. government and assassinate President Trump,” according to charging documents in the Wisconsin case.

The newly unsealed federal court filings indicate that the FBI is investigating Casap in connection to the alleged assassination plot.

The bureau declined to comment on the matter.
