In a Fox News interview, U.S. Attorney General Jeff Sessions said he had no regrets for his decision to recuse himself from the Department of Justice investigation into ties between Russian officials and the Trump campaign.

Sessions, the former Alabama U.S. senator, has come under fire from President Trump for removing himself from the probe but Sessions reiterated his position that, as a participant in Trump's campaign, he could not legally be a part of the investigation.

Sessions will appear on the Fox News show Sunday Morning Futures with Maria Bartiromo. The show, which airs at 9 a.m., will show the full interview.

Fox News tweeted an excerpt of the interview with Sessions in which Bartiromo asked him if he had any regrets about the recusal.

"I believe I did the right thing, the only thing I could do," Sessions said. "I participated in this campaign and as such, under explicit regulations of the Department of Justice, no one can participate in the investigation of a campaign in which they were an active participant."

Sessions appeared on stage with Trump in a rally in Mobile in August 2015 in the early weeks of Trump's push for the White House. He formally endorsed Trump on Feb. 28, 2016 at a rally in Madison, then worked as an adviser with the campaign.

Sessions has also faced scrutiny for his communications with Russian officials during the campaign.

With Sessions' recusal, Robert Mueller was appointed as special prosecutor in the investigation. Mueller announced the indictments of 13 Russian officials in connection with the investigation earlier this week.
