Oregon and Nevada also plan on having National Guard troops on standby to assist local law enforcement on election day.

Ahead of potential civil unrest due to Tuesday’s presidential election, the National Guard is on standby as a precaution in several states, including Washington state and Oregon, where hundreds of ballots were damaged or destroyed after at least three ballot drop boxes were recently set on fire,

The decision by Gov. Jay Inslee comes after ballot boxes were burned in his state and in Oregon, and amid broader concerns about election-related violence.
