This is true: why won’t Trump just say he can’t get a fair trial from this judge and list four reasons and pound on that. He can compare his situation to a “little person” being unable to get justice in the USA.-
You need to read some transcripts of Trump’s actual words. He said precisely and specifically what you are suggesting he ought to have said. Do not expect any mainstream media to tell the truth about Trump. They will lie and distort with absolute consistency.
