This is a thinly veiled attack by Republicans on a cabinet agency they don't like. This is obviously meant to handicap the EPA, not ensure honesty. The science should be publicly available, sure, but peer review already ensures honesty. The data used need not be publicly available. The need to publish full data sets is likely to prevent the acquisition of proprietary data sets in the first place, hindering the ability to even perform the science or use the scientific conclusions. This is the true object of the bill- to disallow policy based on peer reviewed science so when Trump scrubs the data from the EPA, the EPA won't be able to do ANYTHING.
