 Trump himself showed up here late in the night, the first time he's been seen in public since the attempted assassination over the weekend. Welcome the next president of the United States. He did not speak, but he did wave to the crowd and sit with his family in the rear of the convention center. Expected tonight, we should be hearing from Vance for the first time, and also Nikki Haley is expected to speak. Matt Piper, CBS News, Milwaukee.
