Multiple Suspects Charged In Alleged Plot To Attack White House UFC Event
On June 25, a federal grand jury indicted 20-year-old Alexander Iniguez Mercado for his alleged role in a plot to attack the June 14 UFC event at the White House.[1]
Prosecutors say Mercado deleted the Signal app after an FBI call, making key message data unavailable and prompting an obstruction charge that carries up to 20 years in prison.[1] The indictment alleges he served as an administrator and member of Signal groups used to plan the attack.[1] An FBI special agent phoned Mercado on June 13 about online threats; he allegedly denied plans to travel to Washington, refused to meet agents, and then uninstalled Signal.[1] Mercado was arrested June 25 and was set for an initial appearance in Chicago at 3 p.m. Central before U.S. Magistrate Judge Gabriel A. Fuentes.[1]
Around March 2026, a group began recruiting on TikTok under names like 'Vanguard of the Old' or 'Vanguard of the Old Republic' and used Signal to organize about 20 members. Court documents say the conspirators planned to drop explosives from drones and use snipers to shoot people fleeing the scene, while targeting President Trump, Vice President JD Vance, and members of Congress. In Ohio, 19-year-old Tycen Proper purchased an AR-15 in January, a shotgun in June, and more than 1,000 rounds plus body armor using graduation funds.[2]
Mercado is one of eight suspects from multiple states who have been charged in the alleged conspiracy.[1] Social posts and earlier reports credited Proper's mother and the FBI with actions that helped disrupt the scheme before the June 14 event.
The mainstream summary does not mention the specific anti-government and ultra-religious sentiments expressed by the conspirators, which adds a layer of ideological context to their motivations. Court documents indicate that the group referred to themselves as the 'Vanguard of the Old,' highlighting a potentially organized belief system that underpins their actions, a detail overlooked in the mainstream account. Furthermore, while the summary focuses on Mercado's obstruction charge, it does not address the critical role of Tycen Proper's mother, whose alert to authorities about her son's activities was instrumental in disrupting the plot before the UFC event. This highlights a community-level intervention that contrasts with the law enforcement narrative presented in the mainstream coverage.
Additionally, the mainstream summary frames the incident primarily as a law enforcement success, but social media perspectives reveal a more complex view, questioning whether the suspects acted entirely alone. This suggests a broader concern about the rise of decentralized, online-enabled radicalization, which is not explored in the summary but is critical to understanding the dynamics of modern domestic terrorism. The implications of such radicalization are underscored by research indicating a significant increase in radicalized individuals lacking formal group ties, emphasizing the evolving nature of threats faced by authorities today.[3]
