According to a person familiar with the matter, Trump wanted to make a scene and deride reporters at the event but had been told repeatedly by his advisers that it could be the kind of coverage he doesn’t want. Trump also did not know exactly what he wanted his message to be, and his team was taken aback by how many reporters were planning on attending, according to the person, who spoke on the condition of anonymity because they were not authorized to speak publicly about the matter.
“It was going to be awful, awful press,” a Trump adviser said. The adviser, who was not authorized to speak publicly about deliberations surrounding the event, said Trump had originally announced the news conference on a lark and without a plan in place.
