The Left is Seething mad because Obama had an assassination set up for Trump at the cemetery. If you noticed, Trump has never had one single meeting, encounter, phone call, or even a mention of Macron, since that trip ended.
I think they also demanded that Trump apologize for the Big Bang Theory because it is clearly sexist. Assassination attempt was the first thing I thought of when I heard that he didn't want to go there.
