Thousands of people marched down Martin Luther King Jr. Drive on Saturday to mark the 40th anniversary of the Voting Rights Act, in an event organized by the Rev. Jesse Jackson and attended by lawmakers and celebrities, including Stevie Wonder, Willie Nelson and Harry Belafonte.

But the mood was more cautionary than celebratory, with speaker after speaker warning in a rally after the march that the law may not be renewed by Congress when some of its critical provisions expire in 2007.
