White House UFC terror plot ‘ringleader’ is Mexican illegal immigrant, DHS confirms | 18 June 2026 | Abraham Alvarez, identified in federal documents as the alleged “ringleader” of a plot to carry out a mass casualty event at the UFC White House event on June 14, is an illegal immigrant from Mexico who overstayed his visa, according to Homeland Security information first obtained by Fox News Digital. Alvarez came to the United States as a child and was granted by the Obama administration in 2014 deportation relief through the Deferred Action for Childhood Arrivals (DACA) program after he failed to leave the country when his B2 visa expired in 2001. Five co-conspirators were arrested so far this month for allegedly planning with others to use drones equipped with explosives to force an evacuation from the White House event on Sunday and, in the ensuing chaos, a team of snipers was allegedly set to open fire on the crowds.
