A Post investigation — based on government documents and interviews with public officials, ranchers in the valley, farmworkers, and townspeople who live near the alfalfa fields — found that Arizona’s lax regulatory environment and sophisticated lobbying by the Saudi-owned company allowed a scarce American resource to flow unchecked to a foreign corporation.

And it sought to win over its rural neighbors, providing a high school with donations that included Fondomonte-sponsored sports bags and face masks emblazoned with the company logo to protect students from covid.
