1. He was accused of racism in his first job on the national scene
As a US Attorney in Alabama in the 1980s, he prosecuted three black civil rights workers – including a former aide to Martin Luther King – for voter fraud after they led registration drives among the black community. They were acquitted. Civil rights groups accused Sessions of pursuing the case for racist reasons, ignoring similar alleged offences within the white community.
When Ronald Reagan nominated Sessions to be a federal judge in 1986, the Senate heard testimony that Sessions had privately called black civil rights campaigners the NAACP “un-American”, “Communist-inspired” and said it and the American Civil Liberties Union had “forced civil rights down the throats of people”. The witness, government lawyer J. Gerald Hebert, testified that he once told Sessions a white lawyer had been described as a race traitor and that Sessions had said “he probably is”.
2. He ‘joked’ he didn’t mind the politics of the Ku Klux Klan
When Sessions went before the Senate to defend himself, it was put to him he once said he did not mind the white supremacist organisation the Ku Klux Klan “until I found out they smoked pot”. He was accused of saying this by a black prosecutor, who said Sessions had also called him “boy”. Sessions insisted the KKK remark was a joke. The Senate rejected his nomination.
