Obama administration regulators were cooking the books to push leftist agenda

Fox News:

Scientific studies used by the Obama administration to help justify tough environmental regulations are coming under intensifying scrutiny, with critics questioning their merit as the Trump EPA reverses or delays some of those rules.

In one case, agencies determined the research used to prop up a ban on a pesticide was questionable. On another front, the Environmental Protection Agency never complied with a congressional subpoena for the data used to justify most Obama administration air quality rules.

“EPA regulations are based on secret data developed in the 1990s,” Steve Milloy, who served on President Trump’s EPA transition team, told Fox News. “For the EPA, coming up with cherry-picked data is standard operating procedure.”

Milloy, author of “Scare Pollution: Why and How to Fix the EPA,” was previously a lawyer for the Securities and Exchange Commission and is among critics who accuse federal agencies of carefully selecting scientific research to fit a political agenda.

In October, EPA Administrator Scott Pruitt issued a directive to ensure that individuals serving on EPA advisory committees don’t get EPA grants and are free from potential conflicts of interest.

“Whatever science comes out of EPA, shouldn’t be political science,” Pruitt said in a statement. “From this day forward, EPA advisory committee members will be financially independent from the agency.”

Environmental groups blasted the decision.

“Agencies shouldn’t be able to cherry-pick. It’s a problem with administrative procedures across the board,” Logomasini told Fox News. “When money goes to politically active research groups, it’s government funding of the science.”

There is much more with several specific regulations tied to questionable studies.   It appears that in many cases the Obama administration regulators had an agenda and search only for studies that supported that agenda.
