YOU CAN BE SURE HE’S “GROWN” SINCE THEN: Letters from Joe Biden reveal how he sought support of segregationists in fight against busing.

It was more than four decades ago as a battle raged across the country — and in Congress — over sending white students to majority-black schools and black students to majority-white schools often far away from their own neighborhoods. Biden forcefully opposed the government’s role in trying to integrate schools, saying he favored desegregation, but believed busing did not achieve equal opportunity.

In a series of never-before-published letters from Biden, which were reviewed by CNN, the strength of his opposition to busing comes into sharper focus, particularly how he followed the lead of — and sought support from — some of the Senate’s most fervent segregationists.

I wonder who brought these letters to CNN’s attention.
