Akin Gump, the fourth largest lobbying firm in the country by revenue, is being paid to advocate for a polysilicon manufacturer led by an individual whom the U.S. government has linked to China’s repression of the Uyghur people.

In September 2025, Akin Gump entered into a lobbying contract with United Solar Polysilicon to represent its interests on trade policy, according to a March 31 disclosure. United Solar Polysilicon is led by its founder, Longgen Zhang.
