The Senate Judiciary Committee will hear testimony on Wednesday on the future of the Voting Rights Act. In June, the Supreme Court nullified a key provision of the act, ruling the law was outdated.
The decision ended the requirement for more than a dozen states to clear new election laws with the Department of Justice.
Now it's up to Congress to update the formula used to determine which states need extra oversight, based on their history of past voting rights abuses.
The Senate committee will hear from U.S. Representative John Lewis of Georgia, a civil rights leader who led the 1965 peace march at Selma.
"I do feel a major responsibility to do my part in helping to protect the right of all of our citizens to participate in the democratic process," Lewis told Here & Now.
The committee will also hear from Wisconsin Congressman James Sensenbrenner, who led the effort to reauthorize the Voting Rights Act in 2006.
