Ms. Dravis told investigators she declined to reach out to the organization on Ms. Pruitt’s behalf. She also told the investigators that she had cautioned Mr. Pruitt that he would have to disclose his wife’s income on federal financial disclosure documents, and that he responded that he would create a limited liability corporation, according to the two people with knowledge of her interview, both of whom asked not to be identified because of the continuing investigation.

John Konkus, an E.P.A. spokesman, said in a statement that the agency has not spoken with Ms. Dravis or the committee about her testimony, which was reported in The Washington Post. Andrew D. Herman, a lawyer for Ms. Dravis, described her as “remarkably evenhanded” in answering the committee’s questions about Mr. Pruitt’s activities. “She is an honest broker and a very credible witness,” Mr. Herman said. “She’s trying to just tell the truth and get on with her life.”

Cleta Mitchell, Mr. Pruitt’s lawyer who is managing his legal defense fund, said she was not aware of the administrator asking for Ms. Dravis’s assistance. “I don’t know anything about that,” Ms. Mitchell said. Ms. Mitchell, a longtime friend of Mr. Pruitt’s, said in a recent op-ed that she had volunteered her time to find Ms. Pruitt employment. Some E.P.A. officials, she wrote, “may have taken it upon themselves to get involved in her job search.”

The House Oversight and Government Reform Committee is conducting a sweeping inquiry into Mr. Pruitt’s spending, ethics and management of the E.P.A., including his frequent first-class travel and the circumstances of a condo he rented from the wife of an energy lobbyist for $50 a night. There currently are 13 federal investigations, including the committee inquiry, into Mr. Pruitt’s actions at the agency.

Ms. Dravis as well as Ryan Jackson, Mr. Pruitt’s chief of staff, each spoke to the committee last week for several hours, accompanied by lawyers. Mr. Jackson, in an emailed statement, accused the committee of making his discussions public after asking him to remain silent. “It appears they can’t honor their own request,” he said.
