Republican’s wealth boosted by stake in company whose growth linked to China

Financial disclosures show how Ron Johnson's wealth sharply increased thanks to his holding in Oshkosh-based Pacur

The Wisconsin Republican senator Ron Johnson, a vocal critic of Beijing who has vowed to launch investigations into the Biden family's alleged relationships with Chinese businesses, declared $57m in income in his first 10 years in office in connection to his ownership stake in a company whose growth has closely been linked to China.

Financial disclosures show the senator's wealth has sharply increased during his years running for and serving in the Senate thanks to his holding in Oshkosh-based Pacur, a plastics maker where Johnson previously served as top executive.
