Obama not only has NO class. He simply cannot let go of the reins of power.
Here we see him overtly cavorting with his fellow socialist/globalists (Merkel, et al) in an effort to undermine Trump. He has already covertly planted leakers throughout the Intelligence Community, and has also organized and coordinated their efforts with the MSM while changing the laws of intelligence sharing to facilitate the leaks.
He failed as a president - especially on the international stage, so he thinks he gets a Mulligan.
