Mr. Tomlinson said in an interview three months ago that he did not think he had instructed a subordinate to send material on the ombudsman project to Mary C. Andrews at her White House office in her final days as director of global communications, a political appointment.

But the e-mail messages show that a month before the interview, he directed Kathleen Cox, then president of the corporation, to send material to Ms. Andrews at her White House e-mail address. They show that Ms. Andrews worked on a variety of ombudsman issues before joining the corporation, while still on the White House payroll. And they show that the White House instructed the corporation on Ms. Andrews's job title in her new post.

A senior corporation executive who is concerned about its direction under Mr. Tomlinson provided copies of the e-mail messages to The New York Times. Fearing retribution, the executive insisted on anonymity as a condition for providing the copies.

The e-mail messages are part of the evidence being collected in a broad inquiry by the inspector general of the corporation into whether Mr. Tomlinson violated any rules that require that the corporation act as a buffer between politics and programming.

Under investigation are $14,170 in contracts signed by Mr. Tomlinson with an Indiana man who monitored the political leanings of the guests on "Now" when Bill Moyers was its host. And the investigators are looking at $15,000 in payments to two Republican lobbyists last year at the direction of Mr. Tomlinson and his Republican predecessor, who remains a board member.

Mr. Tomlinson declined to respond to questions about the investigation or anything else.
