“In standing with Sanders over Biden, we will declare that we are not going backward — we are going forward into a future of empowerment and equality for all,” she added.

The former Ohio state senator contrasted Biden and Sanders throughout her piece, saying that Biden started his career with personal letters to pro-segregation senators to support legislation preventing black students from attending schools with white students.

She criticized the vice president’s earlier ideas surrounding welfare reform, crime reform and economics as a Delaware senator, saying that Sanders was on the right side of history by disapproving of Biden’s approaches.

“And today the differences between Biden and Sanders remain stark,” she wrote, citing their views on marijuana legalization, Medicare for All and student loan forgiveness.

The op-ed was published in one of the early voting states with a high amount of African American voters. So far in polls, Biden has maintained a plurality of African American support and the lead in South Carolina.

Biden at the time called the senator's comments a "mischaracterization" of his views, saying he took issue with the Department of Education managing the busing policies.

Harris saw increased support after the first debate, but dropped out of the presidential race after it lagged.

In 1974, Sanders told the Middlebury College campus newspaper that he believed busing risked producing racial hostility where it didn't previously exist.

"The government doesn't give a shit about black people," he said.
