ROANOKE, Va. -

The Roanoke Branch of the NAACP marked the 50th anniversary of the Civil Rights Act Wednesday with a call for action.

Members of the group say a supreme court ruling last year severely weakened landmark legislaton that protects voting rights.

They held a news conference Wednesday morning outside the Roanoke office of 6th District Congressman Bob Goodlatte.

Along with leaders of the Southern Christian Leadership Conference, they asked the chairman of the House Judiciary Committee to call a hearing on a proposed amendment.

Brenda Hale is the President of the NAACP Roanoke Branch. "Discrimination is taking place. Voting rights are under attack in this country," Hale told WDBJ7 in an interview. "And we have to stand up now, bring these issues to the table."

Goodlatte has met with leaders of the civil rights group, and says he fully supports protecting the voting rights of all Americans. "As Congress determines whether additional steps are needed to protect those rights," Goodlatte said in a written statement, "I will carefully consider legislative proposals addressing the issue."
