 rumored to be on his short list for a running mate. CBS's Olivia Rinaldi is in Miami. Senior campaign advisors who tell me that pick could come as soon as 10 minutes from now or one minute before the convention. And even Donald Trump himself has talked about that pick last night on Sean Hannity. He teased and said he still doesn't know who he's going to pick and he still doesn't know when he's going to announce it.
