Pruitt conceded that his agency should take "concrete action" related to chemicals like PFAS, but testified that he was unaware of any delay in the release of the study. At a May 2018 "leadership summit" on PFOA, PFOS and related chemicals attended by Pruitt, some reporters were barred from attending, including those from "Politico" (which first reported on the release of the emails), CNN, and E&E News (which writes on environmental issues). An Associated Press correspondent, Ellen Knickmeyer, was physically ejected from the meeting room, and U.S. Representative Dan Kildee of Michigan, who represents a district dealing with the Flint water crisis, said that a member of his staff was barred from the meeting. Kildee wrote to the EPA's inspector general to ask whether any open meetings laws were violated. An EPA spokesman asserted that the summit was not subject to the Federal Advisory Committee Act. Senator Tom Udall, in response, wrote a letter to Pruitt stating, "This intimidation of journalists seeking to cover a federal official presiding over important policy-making is un-American and unacceptable. ... Clean drinking water is a public health issue that does not belong behind closed doors."
