The Justice Department and FBI say they will have officials ready on Election Day to respond to potential crimes.

Justice Department officials will be monitoring conduct at certain polling places, and lawyers will be available to handle complaints regarding voter intimidation, discrimination and fraud such as vote-buying.

The FBI will also have a command center to monitor potential security threats related to the election. U.S. intelligence officials have warned of Russian efforts to use hacking to interfere with the election process.

The Justice Department has already warned that it will have fewer observers at the polls than in 2012 because of a Supreme Court opinion that gutted a key provision of the Voting Rights Act.

The exact number of observers will not be revealed until closer to Election Day.
