On the eve of Martin Luther King Day—just moments before the start of the Democratic presidential debate in South Carolina—John Edwards’ campaign released a letter sent by King’s son, Martin Luther King III, to the former North Carolina senator, praising him for his commitment to end poverty and injustice and calling for all candidates to emulate his initiative.

“I want to challenge all candidates to follow your lead, and speak up loudly and forcefully on the issue of economic justice in America,” King wrote. “My dad was a fighter…Keep fighting. My father would be proud.”

Edwards and King held a private meeting at the King Center in Atlanta on Saturday, and though details of that encounter were not disclosed to the press, the two men discussed Dr. King’s legacy and their “shared commitment to fighting poverty,” according to Mark Kornblau, a spokesman for Edwards’ campaign.

In his letter, King addressed the aims of Edwards’ campaign mission: “I appreciate that on the major issues of health care, the environment, and the economy, you have framed the issues for what they are - a struggle for justice. And, you have almost single-handedly made poverty an issue in this election.”

The letter could not have come at a more opportune time for Edwards, who was asked at the end of Monday night’s debate, “If Dr. Martin Luther King were alive today…why do you think he would or why should he endorse you?”

Without hesitation, Edwards said he has focused his cause on the “two biggest issues that Dr. King stood for, which are the issues of equality and ending poverty in America.”
