Analysis of the claim:

• Federal authorities did arrest five suspects in connection with a foiled domestic terror plot targeting the UFC Freedom 250 event at the White House. The arrests were announced on June 16, 2026¹²³.
• The event was held on June 14, 2026, not June 16, 2026. The UFC Freedom 250 event took place on the South Lawn of the White House on Sunday, June 14, 2026, which was President Trump's 80th birthday and Flag Day⁴⁵.
• The names are partially misspelled. The suspect from California is "Bryan Omar Roa," not "Brian Omar Roa." The suspect from Ohio is "Tycen C. Proper" (19), not "Tyson Proper." Only "Michael Alan Thomas" is spelled correctly in the claim¹⁶.
• The plot details are accurate. The conspirators allegedly planned to use drones armed with explosives to force an evacuation, then deploy snipers to fire upon "high-value targets" in the fleeing crowd⁷¹⁶.
• Five suspects were indeed arrested: Tycen C. Proper (Ohio), Bryan Omar Roa (California), Michael Alan Thomas (California), Daniel K. Eskridge (Missouri), and Abraham Hermosillo Alvarez (Nebraska), who was identified as the ringleader¹⁶.
• The FBI learned of the threat on June 10, 2026, after Proper's mother contacted police about her son's firearms purchases and disturbing behavior¹⁶.
