Pelosi is very effectively trolling him. He's good at playing victim but she somehow manages to bring him to rage.
Anyone can bring him to rage. Absolutely anyone. Every single time someone says something disparaging about him or says anything he disagrees with he comes out in force with a raging Tweet full of personal insults or he gives a press conference or slams them at one of his rallies. He never forgets either, (or he does, but then it comes back to him again) hence his 30 year war with the owner of Vanity Fair over the tiny hands comment.
In the same way, if you praise him, his insecure ass loves it and he acts like he will do anythjng for people who big him up. I don't think the Dems have played on any of this enough, neither have the press. If anything, they have acted in an even dumber manner than he has, which is saying something.
