Federal officials have charged multiple people who they claim discussed plots to attack the UFC fight night event at the White House, including by using drones and a gunman.

A team including the Secret Service and FBI uncovered messages discussing the plot between multiple individuals, according to criminal complaints against five people unsealed Tuesday.

According to a criminal complaint against one of the alleged plotters, the mother of one of the defendants — 19-year-old Tycen Proper — called local police on June 10, saying she was “was concerned about her son” because of his recent conduct, which included buying guns and communicating with a group of radicals online.

Proper’s mother had also seen her son researching mapping locations in Washington, DC, near the White House, according to the complaint, and told officers that her son had said the group was looking at multiple locations for “recon” and “hit and run missions.”

According to court documents, the group Proper joined was focused on some form of accelerationism — an ideology that believes the collapse of society should be expedited in order to form a better world.

Some members said in the chats they didn’t want people connected to Jeffrey Epstein running the country, according to the complaint, while Proper was also focused on targeting lawmakers who were pro-Israel.
