Several experts have said that Trump's witness Robert Costello, who was supposed to be helping Trump, by trashing Michael Cohen.

Shockingly Robert Costello is a lawyer, so he should know he needs to affect the jury's thinking about Michael Cohen, but in reality made Trump look worse.

I have no doubt that Trump insisted Costello take the stand to vent Trump's feelings, transferring Trump's anger onto the judge.

At one point, Costello remarked “jeez” when he was cut off by an objection. He also called the whole exercise “ridiculous.”
