No, that’s not correct. You are receiving delusional propaganda about disallowing expert witnesses from somewhere. Where is that from?
Bradley Smith was definitely allowed to testify as an expert, but the defense declined to call him. Here, since you like pretending to have read things direct from the court. He was not allowed to show up and instruct the jury, which is the same as decided in the prior cited cases in NY and OH.
Where is your delusional propaganda from? The things you are claiming are lies that Donald has been tweeting. So perhaps your delusions are coming direct from the source: a lifelong con man and fraud who committed election interference in 2016.
