Not sure what’s going on but a President should not be misspeaking when conducting a joint interview with the leader of Russia.
I can’t imagine something like this ... “Tear down this wall ... (later) I misspoke. I mean dismantle the wall some but not all of it. Oops. My bad.”
... But let’s see what Trump actually says.
Monday morning quarterbacking, huh? You stand up there and make sure you don’t misspeak and word everything precisely so EVERYONE fully understands exactly what you mean and there is no room for twisting and all the while not insulting the world leader standing beside you who could start WWIII in a split second.
