Mayor Eric Garcetti's’ former deputy mayor, Raymond Chan, solicited donations from Chinese developers who wanted to build downtown. Now there are questions about whether that was pay-to-play. Chan no longer works for the city. But he and about two dozen people are being investigated by the FBI for alleged bribery, extortion, money laundering, and kickbacks. A couple of years ago, he was one of two men overseeing the mayor’s economic development plans. Emails from that time show Chan asking for donations to a charitable organization from companies waiting for city approval for their projects.
