The U.S. Department of Justice has launched the largest election monitoring effort in its history, deploying approximately 1,000 monitors and observers across all 50 states for Election Day.

The nationwide effort, coordinated by the DOJ’s Civil Rights Division, includes monitors on the ground in New Jersey’s Bergen, Middlesex and Union counties.

It marks the first time DOJ observers are present in every state to monitor compliance with federal voting rights laws.

Personnel from the Civil Rights Division and U.S. attorneys’ offices, along with federal observers from the Office of Personnel Management, are staffing polling locations and remaining in contact with state and local election officials throughout the day.

Federal officials advised that any immediate disruptions, violence or physical intimidation at polling sites should be reported first to local police by calling 911, then to election workers on-site.
