From Politico:
“In USDA, we want good scientific discovery,” [USDA Secretary Sonny] Perdue said, when asked about the mandated research-disclosure language. “We want peer-based evidence there. We know that research, some has been found in the past to not have been adequately peer-reviewed in a way that created wrong information, and we’re very serious when we say we’re fact-based, data-driven decision makers. That relies on sound, replicatable science rather than opinion. What I see unfortunately happening many times is that we tried to make policy decisions based on political science rather than on sound science.”
