Zimmerman's investments in Russia made national headlines in 1997 when the USAID ended a $14 million grant to the Harvard Institute for International Development, headed by Zimmerman's husband, after he was accused of using the institute to help Zimmerman with her investments. As part of a settlement, Zimmerman subsequently paid $1.5 million to the USG through one of her companies, Farallon Fixed Income Associates. Neither Zimmerman nor her husband admitted wrongdoing.
