UPDATED, 2:42 p.m.: The One City Summit fell short of attendance expectations, drawing a crowd of about 1,700 to the Walter E. Washington Convention Center even though organizers said they had registered 3,211 people for the daylong meeting. In an email to The Washington Examiner, mayoral spokesman Pedro Ribeiro said attendance was “1,700+,” but offered no further details. Earlier in the week, Ribeiro said America Speaks, the nonprofit that facilitated the meeting, expected 60 percent of registered participants – 1,927 people – to show up for the meeting. Saturday’s actual attendance meant that a maximum of 56 percent of registrants ultimately participated in the summit.
