It's US Senate Minority Leader Mitch Mcconnell and during a public adress he froze in the middle of a sentence and just stared blankly into the distance for 20 seconds or so before being escorted away.
A few minutes later, he came back and pretended that this is a normal thing that ever happens to people with brains that aren't broken.
I do this all the time, although admittedly not when speaking to others... It's useful for problem-solving if one gets stuck, a little while of no thinking clears the board and allows thoughts to again wander new paths. It's also useful for preventing headaches from muscle tension!
Apologies, I read it wrong. I saw American politician in a meme and thought it was some more shit giving to a certain person. I block all political communities because I don't want to see it.
