'All deserve to die': Bomb threat at conservative anti-Trump summit blamed on Proud Boys

A bomb threat that allegedly came from the Proud Boys interrupted a summit of conservatives who oppose President Donald Trump.

Minister and democracy advocate Reed Howard shared an announcement about the threat at Sunday's Principle's First Summit, which was set to include speakers like former Rep. Adam Kinzinger (R-IL) and former Trump administration official John Bolton.

"A bomb threat claiming to be the Proud Boys disrupted the #PrinciplesFirst Summit today—an event dedicated to democracy, character, & the rule of law," Howard wrote on X (formerly Twitter).

"Good thing we won't be intimidated by the weak boys," Kinzinger responded.

Former CNN anchor Jim Acosta shared a manifesto from a person allegedly behind the threat.

"To honor the J6 hostages recently released by Emperor Trump, I've constructed four pipe bombs out of 1x8-inch threaded galvanized pipes, end caps, kitchen timers, some wires, metal clips and homemade black powder," the message said.

"Mark Cuban, Chris Christie, John Bolton, George Conway, J. Michael Luttig, Adam Kinzinger, Michael Steele, Geoff Duncan, Bill Kristol, f----t Frank Figliuzzi, Glenn Kirschner, Stephen Richer, Norm Eisen, and especially Michael Fanone all deserve to die," the threat added, calling out speakers at the conference. "To my family: I simply did what needed to be done. MAGA."
