Sen. Al Franken declined to say that Attorney General Jeff Sessions lied to him when Sessions said during his confirmation hearing he had no contacts with Russian officials during the 2016 campaign, which later proved to be incorrect.

“Lie is knowingly telling an untruth. I would like to give him some benefit of the doubt,” the Democratic Minnesota senator said on ABC’s “This Week” Sunday. “If he lied knowingly then he committed perjury, so I don’t want to go there and definitively say that we should be prosecuting the attorney general.”
