National Harbor officials say they are hammering out the details of plans to preserve free-speech rights in public spaces at the $2 billion Prince George’s County development.

The plans are still in draft form and are not yet available, said Andre Gingles, an attorney for National Harbor, but they will include a code of conduct and a permitting process for protests. That process could become important when controversial groups rent convention rooms at Gaylord National Resort, event planners say.
