i want to bring in brianna keilar, she's also here inside the debate hall with more on what is going on. what are you see something. >> well, i can tell you a little bit about what has been going on for some of the candidates. hillary clinton has been doing last minutes debate stage. she didn't come on the stage. this will allow the campaign to really have the visuals of hillary clinton for this week, this debate week, be very tightly controlled. allowing that visual of her going to trump tower and standing by union members who are picketing and making an impact that way. and then also her debate performance and then what is really sort of a phrenetic travel pace that she will do over the next four days post-debate travel in a number of states. so she's been preparing today really just the last of it. she's been preparing for really into september.
