Scott Pruitt, the administrator of the Environmental Protection Agency, gave a political aide the task of helping him seek a “business opportunity” for his wife with the fast-food chain Chick-fil-A.

Emails released to the Sierra Club under the Freedom of Information Act show that Sydney Hupp, a former scheduler for Mr. Pruitt, contacted Chick-fil-A’s chief executive, Dan T. Cathy, in May 2017 at Mr. Pruitt’s behest to set up a meeting.

After a back-and-forth in which Ms. Hupp initially said the administrator “didn’t mention a specific topic” of discussion, she told the company’s director of regulatory affairs that Mr. Pruitt’s request was of a personal nature. “The Administrator would like to talk about a potential business opportunity with Mr. Cathy. Nothing very pressing, just hoping to connect sometime in the next month or so,” Ms. Hupp wrote.

Mr. Pruitt ultimately spoke by phone with Chick-fil-A representatives.

Mr. Cathy, reached by phone, referred questions to a company spokeswoman, Carrie Kurlander. Ms. Kurlander said she would not comment further. In an email to The Washington Post, which first reported Mr. Pruitt’s effort to seek a business deal with Chick-fil-A, Ms. Kurlander had said the call was about the possibility of Mr. Pruitt’s wife, Marlyn, opening a franchise of the fast food chain. Ms. Kurlander told the Post that Mrs. Pruitt never completed the franchisee application.
