New York City officials ordered Wall Street protesters to clear their sleeping bags and tarps from the park where they started a movement that has spread around the globe and forced CEOs and presidential candidates to take notice. Demonstrators said they wouldn't be going anywhere Friday morning, setting the stage for a showdown with police. The owner of the private park where the demonstrators have camped out for nearly a month said it has become trashed and unsanitary. Brookfield Office Properties planned to begin a section-by-section power-washing of Zuccotti Park at 7 a.m.
