Wisconsin's Democratic members of Congress want the U.S. Justice Department to oversee the state's monitoring of the election due to concerns with the new voter ID law.
The four Democrats sent a letter Wednesday to U.S. Attorney General Loretta Lynch asking for the oversight. It was signed by Sen. Tammy Baldwin and Reps. Gwen Moore, Mark Pocan and Ron Kind.
This is the first presidential election in Wisconsin where voters will be required to show photo IDs at the polls.
The lawmakers say they believe the law is flawed and puts in jeopardy the ability of some people to vote. They say they are particularly concerned about protecting the voting rights of people of color.
They also say they are worried about voter intimidation at polling places.
