SAN DIEGO -- The lawyer who is leading the San Diego Chargers' efforts to move to Los Angeles was vigorously booed as he addressed the crowd at the beginning of a public hearing the NFL mandated as part of the relocation process.

"Why don't you tell the truth?" one fan yelled at Mark Fabiani, who has criticized Mayor Kevin Faulconer's efforts to build a new stadium in Mission Valley to replace aging Qualcomm Stadium.

Eric Grubman, the NFL's point man on Los Angeles, had to step in and ask that the crowd to calm down.

The Chargers and their rivals, the Oakland Raiders, have proposed a joint $1.7 billion stadium in Carson, an industrial suburb of L.A. if they don't get stadium deals in their home market. Their proposal was announced after St. Louis Rams owner Stan Kroenke announced plans for a stadium in Inglewood.

"It's good to see all of you here tonight," Fabiani, a one-time deputy mayor of Los Angeles, told the crowd Wednesday night at a downtown theater.

"That's a lie," one fan yelled.

Fabiani, who works for Chargers chairman Dean Spanos, blamed politicians, not the fans, for the team's stance. The Chargers walked away from negotiations with the city and county in mid-June. Fabiani said the team won't accept Faulconer's proposal because of a "flawed fatal EIR process."

Fabiani has criticized the city's environmental impact report. However, Gov. Jerry Brown recently approved an accelerated judicial review process for any lawsuits filed.

Faulconer's proposal caps public contributions at 32 percent and makes the team responsible for overruns. Fabiani has said the team wants at least a 60-percent public contribution.

City Councilman Scott Sherman gave an impassioned speech. He said Fabiani's claims that the city hasn't been able to accomplish anything "is the furthest thing from the truth."

Sherman said that while city leaders have come and gone, "the one constant is Mr. Fabiani's employment of the San Diego Chargers. He has been nothing but negative the whole time."

A similar hearing was held Tuesday night in St. Louis and one will be held Thursday night in Oakland.

The San Diego hearing came three days after the Chargers were embarrassed at home by the Raiders, 37-29. The game drew at least 50 percent Raiders fans.
