Ahead of Election Day on Nov. 5, leaders in the Pacific Northwest are preparing for potential public safety concerns.

National Guard personnel in 20 states and the District of Columbia have been activated or are on standby to aid local authorities ahead of Tuesday’s election, Pentagon officials said Monday. Around 125 National Guardsmen in 10 states have been activated for election support so far,

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,

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

The National Guard has hundreds of troops activated or on standby across the country to defend against cyber attacks and support operations during Tuesday’s presidential election.

A few states have said they will have the National Guard on standby as a precaution for potential civil unrest on Election Day after ballot drop boxes were set on fire last week.

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.

The Department of Homeland Security had previously warned that threats to election infrastructure were high this election cycle.

Washington’s National Guard is now on standby for unlawful activity related to the election, but officials are saying very little about what that means.
