One man was spotted singing into a bullhorn and blowing into a shofar to demonstrate his support for Trump.

Another demonstrator played the bagpipes.

And amid all the chaos, Rep. Darrell Issa (R-Calif.) was spotted jumping over a fence to get into the building.

RNC Chairman Reince Priebus later tweeted that it was a "great" meeting that was a "very positive step toward party unity."
