Story highlights Franken said he thought the Attorney General committed perjury

Sessions has denied wrongdoing

Washington (CNN) Minnesota Sen. Al Franken said he now believes that Attorney General Jeff Sessions committed perjury during his confirmation hearing when he did not disclose meetings with a Russian ambassador.

Sessions' response during the hearing to Franken's question about Russia and President Donald Trump's campaign was demonstrably false, Franken said Tuesday on CNN's "The Lead" with Jake Tapper.
