The problem is that he is surrounded by sycophants, who for Political reasons nod and say yes to everything, those that don’t soon find themselves out of a job.
I suspect that they all sign a gagging order so we will never know the truth.
Im sure that he had/ still has Covid, was pumped full of drugs to get him onto the balcony ( the man needs public adoration, or ridicule, as long as it’s publicity) and then is either in bed in the White House or is busy spreading his germs around, he really doesn’t care either way, the public won’t find out.
He is so protected in his job that he really seems to be invincible, let’s hope the voters get him out, but I doubt it.
