In a statement shared with Mashable, John T. Kelley, vice president and show director of CTA, acknowledged security concerns following the explosion of a Tesla Cybertruck outside the Trump International Hotel Las Vegas on New Year's Day.

Authorities believe the Special Forces soldier’s suicide bombing was designed to draw attention to his various complaints and claims.
