Donald Trump's strategy for fending off scandals and accusations against him is always the same: accuse others for having the flaws he himself possesses, and claim that other people committed the same kind of crimes that he very obviously did himself.
It's about as mature as saying "I know you are, but what am I?", and it's equally telling and ineffective. He has no other strategy, he is unable to learn anything new, and with his currentbdecline in mental capacity, it's doubtful that he even realizes that he is losing.
