The man who exploded a Tesla truck outside Trump's Las Vegas hotel wrote of “political grievances,” armed conflicts elsewhere and domestic issues in the days leading up to his suicide, officials said Friday. Via CNN: The writings were found in the cellphone of Matthew Alan Livelsberger, the truck’s driver, said Sheriff Dori Koren of the Las Vegas Metropolitan Police Department in a news conference. In his writings, the driver of the Cybertruck said the incident was intended not as a “terrorist attack” but rather “a wake-up call,” according to police.
