Mitch has been undermining and backstabbing President Trump from the beginning of Trump’s administration. sometimes openly, but mostly in the dark.
Recall how he kept the senate in session always so Trump could not make recess appointments,
When I happened to tune in to part of that speech, my thoughts were, what in the heck does he think will accomplish with this? That was a time to let the rhetoric cool down, but he amped it up to new levels.
I believe that Trump was coming to close to McConnell’s illicit operations with China. The family fortune, and perhaps that of other Republican senators, was in danger.
