This is all about keeping Trump from holding a rally there.
Trump needs to force the issue.
Trump has an option, he can hold the Rally on Federal land and Cooper cannot do a thing about it. Large outdoor stadiums at Fort Bragg and Camp Lejeune. Lejeune opens up once a year and lets civilians in for the Fourth of July. The event is great but so big I stopped going when I no longer had an office on the base. Thousands of non-DOD ID card holders come on base. It would be a limited rally (3000) but they could social distance outside the stadium with a big screen setup and have 1000 on the lawn and parade deck next to the stadium. The President can legally hold the event for the military but open it up to civilians. Tour the Tri-Base area and Bragg, have Melania meet with military wives and then give a military centric speech but open the event to the public.
