I first ran for the Fremont City Council in 2008 on a platform of not accepting donations from developers nor corporations. I won a seat on the City Council on my third try in 2012 and served there until 2020. As a Councilmember, I brought forth progressive referrals on minimum wage acceleration, rent stabilization, cannabis delivery, sanctuary city status and Proposition 13 reform.
I served as an associate member on the Alameda County Democratic Party Central Committee from 2010 to 2012. I was an elected member of that body from 2012 through 2020. I've attended every State party convention since 2013.
"Chinese spy connection"
A suspected Chinese intelligence operative developed extensive ties with local and national politicians, including a U.S. congressman, in what U.S. officials believe was a political intelligence operation run by China’s main civilian spy agency between 2011 and 2015, Axios found in a yearlong investigation.
The woman at the center of the operation, a Chinese national named Fang Fang or Christine Fang, targeted up-and-coming local politicians in the Bay Area and across the country who had the potential to make it big on the national stage.
Through campaign fundraising, extensive networking, personal charisma, and romantic or sexual relationships with at least two Midwestern mayors, Fang was able to gain proximity to political power, according to current and former U.S. intelligence officials and one former elected official.
Even though U.S. officials do not believe Fang received or passed on classified information, the case "was a big deal, because there were some really, really sensitive people that were caught up" in the intelligence network, a current senior U.S. intelligence official said.
Private but unclassified information about government officials — such as their habits, preferences, schedules, social networks, and even rumors about them — is a form of political intelligence. Collecting such information is a key part of what foreign intelligence agencies do.
Between 2011 and 2015, Fang's activities brought her into contact with many of the Bay Area’s most prominent politicos.
Fang helped with a fundraiser for Rep. Tulsi Gabbard (D-Hawaii) in 2013, according to a flyer from the event Fang shared on Facebook. Others on the bill included Hon. Raj Salwan, Hon. Vinnie Bacon, Hon Aisha Knowles, Mihir Meghani and Marie Mao.
