“In case you haven’t noticed, there are a lot of people here," Sanders, who was born in Brooklyn, said at the outset of his remarks.
The largest crowd count for the senator from Vermont before Sunday had come at a August rally in Portland, Ore. The staff at the venue estimated that 28,000 people attended that event.
Aides to Sanders said Sunday’s crowd totaled 28,356. The figure was attributed to a representative from a company that helped produce the event. Aides said the company also works for Clinton’s campaign.
Michael Briggs, a Sanders spokesman, said the count included about 26,000 people who made it into a large cordoned-off area as well as some who watched from outside the perimeter.
