One thing that my raises suspicions that they are together is that the jointly appear at each others book launches and signings. I can understand if they show up to a book store together in NY or D.C. as that's where they live and frequently visit for work. It can be treated as a joint promotional effort. But when they started appearing in places the require significant travel/out of the way together on weekends seemed a bit much for coworkers. Then there was the issue of Joe and Mika being down at Mar a Lago on New Years Eve meeting with President Elect Trump. They claim it was so they could talk to him and persuade to get an interview but the fact that it was a holiday and at an exclusive resort seemed odd. Surely they could have been lobbying to get an interview during the many conversations Joe says he has with PEOTUS and Mika has been seen visiting Trump Tower. If I'm wrong I'm sorry but some of their behavior seems like they are a couple. I think (don't hold me to it) I read that some of the agreements that NBC has to provide a certain amount of news content per week. Keeping KLG and Honda under the news umbrella would meet that goal as they talk about current events and interviews.
