Democrats sense blood in the water, but there is nothing to see here.
Sessions as member of the Armed Services Committee was free to meet with any heads of state he felt a need to. Whether he talked about the campaign is absent is absent any evidence. Session denies that happened, so unless someone has a tape (John McCain), this is a non-story.
Franken's question to Session is key, Session was NOT a member of the Campaign, and to my knowledge there is no law preventing a Republican - who would naturally be for the Republican candidate for president executing his duties as a member of the ASC from doing his job. Thus, false story, based on parsing of words.
