"WASHINGTON — President Trump’s Environmental Protection Agency was rushing to complete one of its last regulatory priorities, aiming to obstruct the creation of air- and water-pollution controls far into the future, when a senior career scientist moved to hobble it.
Thomas Sinks directed the E.P.A.’s science advisory office and later managed the agency’s rules and data around research that involved people. Before his retirement in September, he decided to issue a blistering official opinion that the pending rule — which would require the agency to ignore or downgrade any medical research that does not expose its raw data — will compromise American public health.
“If this rule were to be finalized it would create chaos,” Dr. Sinks said in an interview in which he acknowledged writing the opinion that had been obtained by The New York Times. “I thought this was going to lead to a train crash and that I needed to speak up.”"
