Will Trump say "border czar" at Wisconsin rally?

Donald Trump has scheduled a rally to be held on September 7 in Mosinee, Wisconsin. This market will resolve to "Yes" if Trump says "border czar" during their appearance at this event. Otherwise, the market will resolve to "No". Any usage of the phrase regardless of context will count toward the resolution of this market. Pluralization/possessive of the phrase will count toward the resolution of this market, however other forms will NOT count. If this candidate does not appear at this event, or if the event is otherwise cancelled or delayed beyond September 7, this market will resolve to "No". The resolution source will be the video of the speech.
