“I believe I did the right thing, the only thing I could do. I participated in this campaign, and as such, under the explicit regulations of the Department of Justice, no one can participate in an investigation of a campaign in which they were an active participant,” Sessions said on Fox News’s “Sunday Morning Futures.”

“You can’t ask other members of the department to follow the law and follow the rules if the attorney general himself refuses to do so,” he added.

Trump reportedly directed White House counsel Don McGahn to stop Sessions from recusing himself.

Meanwhile, Trump and some Republicans have in recent weeks leveled accusations of political bias at the Justice Department, citing anti-Trump messages exchanged between FBI employees and other allegations outlined in a GOP-crafted memo.

Fox News host Maria Bartiromo asked Sessions how he would “turn the ship around” at the Justice Department following claims of political bias.

Sessions didn’t directly address the specific allegations Bartiromo laid out, but said he’s setting a tone of professionalism in the department, and praised the work of new agency officials like FBI Director Christopher Wray.

“We’ve made other changes within this department that I think will put us on a path to fulfill my responsibility to the American people and that is to conduct our work professionally, honestly and without political bias,” Sessions said.
