"There seems to be no bottom to this ethics catastrophe with Scott Pruitt".
Pruitt was also under fire this week by a conservative nonprofit group from Iowa, which created a 30-second television ad this week and said "for the good of the country, Pruitt must go".
A spokeswoman for Inhofe later told Reuters that while the senator is not ready to call for resignation, "he has concerns about the reports coming out and wants to hear directly from Pruitt" in a hearing.
EPA Administrator Scott Pruitt testifies before a Senate Appropriations Interior, Environment, and Related Agencies Subcommittee hearing on the proposed budget estimates and justification for FY2019 for the Environmental Protection Agency on Capitol Hill in Washington, U.S., May 16, 2018.
The EPA typically does not disclose Pruitt's whereabouts, and did not publicize Pruitt's trip to South Dakota on Wednesday until a tweet from shortly after 3 p.m. from Pruitt's official account.
Duff said Pruitt's visit, which made South Dakota the 35th state he's been to during his time in office, came at an ideal time, as it coincided with a national discussion about ethanol. The EPA head said petitions have been lodged asking the agency to revisit the finding, calling its passage in 2009 a "breach of process". "So, you know, we could - that might be a good swap". "They have a methodology; they have formulas", he said.
EPA, he said, should have "done its own homework", and the agency is now evaluating how the process was conducted.
Inhofe used to chair the committee and now chairs one of its subcommittees.
"A spike? That's more than a spike".
Via Twitter, Pruitt said the meeting was "candid and productive".
"Biofuels policy has an important impact on the value of the crops we produce on our farm", he said. "I am sending over a communication today that says we have had enough of these things". Other topics included the commitment to cooperative federalism, reforms to the EPA's Regional Haze Program and permitting improvements.
Leo is a prominent Pruitt backer and longtime friend who was involved in arrangements for the administrator's visit to Italy past year. He specifically cited President Donald Trump's repeated promises to both continue the Renewable Fuel Standard and to make E15 fuel available year-round.
Also discussed was the Waters of the USA rule and a sorghum oil pathway rule.
Wednesday was a particularly newsy day regarding Pruitt, even though he was in South Dakota.
