Federal election monitors are watching the polls in Jefferson, Montgomery and Mobile counties on Tuesday as part of the largest election monitoring operation in the Justice Department’s history.

The department announced Tuesday morning that approximately 1,000 monitors and observers are deployed across all 50 states, the first time the DOJ has covered every state in one election. Alabama’s three counties are among roughly 160 jurisdictions on the list.

“Election integrity has been one of the top priorities for this Administration and this Division,” said Assistant Attorney General Harmeet K. Dhillon, who leads the Civil Rights Division. “I am very proud we are deploying the largest monitoring effort in DOJ history, and pursuing transparency for elections in an assertive and nondiscriminatory manner.”

The monitors include Civil Rights Division staff, personnel from other DOJ components, U.S. Attorney’s Offices and federal observers from the Office of Personnel Management.

The department said they are checking compliance with the Voting Rights Act, the National Voter Registration Act, the Help America Vote Act, the Americans with Disabilities Act and federal statutes against voter intimidation.

The DOJ has sent monitors to polling places in every administration since 1965.

Secretary of State Wes Allen, Alabama’s chief elections official, said in a statement Tuesday morning that the state’s probate judges, circuit clerks, sheriffs, boards of registrars and poll workers are “ensuring that our elections are conducted in a fair, secure, and transparent way.”

The DOJ said voters with complaints about polling place disruptions should contact local election officials first, and report threats or intimidation to local police by calling 911. Its election hotline is 1-800-253-3931.

Polls are open until 7 p.m. Anyone in line at 7 p.m. will be allowed to vote. Voters who need their polling place can check myinfo.alabamavotes.gov.
