Axios reported on Monday that a Chinese national named Fang Fang or Christine Fang targeted up-and-coming local politicians, including Swalwell, D-Calif. According to Axios, investigators became so alarmed by Fang’s behavior and activities that they alerted Swalwell in 2015 to their concerns, and gave him a “defensive briefing.” Swalwell then cut off all ties with Fang and has not been accused of any wrongdoing, according to an official who spoke to the outlet.
