Conservative Newt Gingrich, a former House speaker, and the Rev. Al Sharpton, a liberal, said on the 55th anniversary of Brown v. Board of Education that they will work together to reduce racial and socio-economic gaps in achievement. "I know it's possible to educate every child from every background," Gingrich said at a Washington, D.C., rally. "We're not telling you what the answer is. But we're telling you to keep changing until you find a solution."
