It's obvious this shit bothers him, that's why our President is always tweeting about this inconsequential BS, feeding his base, while further degrading any integrity that may have been left in the office of the Presidency, already in tatters since the 90's.
I think that obummer's roast of him in the audience in 2011 set him on a mission, he did it.
Now he oftentimes reminds me of the cat that actually caught it tail.. Thanks Trumpers.
