Some of the gung-ho Weiner crowds, including at the Aug. 11 Dominican Day Parade in Manhattan, were really actors who were paid $15 an hour by the California firm Crowds on Demand, according to a source with direct knowledge of the deal.

The source said surrogates for Weiner approached the Santa Monica-based company days after Indiana-native Sydney Leathers came forward to say that Weiner had continued his digital dalliances after resigning from Congress.

The campaign asked the company to have actors seem “like either supporters or people who met him and became supporters as a result of that encounter,” the source said.
