Maybe there were more questions on this subject than Franken's. However, Franken's was what Sessions  "would" do if “anyone affiliated” with the campaign had been in contact with officials of the Russian government. That "would" could mean right now, here, or - more likely - it meant, What would you do if you were AG and you found out something? In either case, Sessions did not answer that question and seems to have volunteered answers to questions that were not asked. He got himself into this and didn't have to.
