The Washington Post reported erroneously that Daniel Fefferman, an official of the Rev. Sun Myung Moon's Unification Church, had refused to answer a House subcommittee's questions about the South Korean Central Intelligence Agency's involvement in Moon's National Prayer and Fast Committee. In fact, the subcommittee did not say that Fefferman had refused to answer such questions.

A House subcommittee reported yesterday that it has found "reliable information" showing that the Rev. Sun Myung Moon has maintained "operational ties" with the South Korean Central Intelligence Agency.

The subcommittee also suggested - through a vague press release - that the South Korean government may have been involved in Moon's efforts in 1974 to arouse U. S. public opinion agaist the proposed impeachment of President Nixon.

Rep. Donald M. Fraser (D-Minn.), chairman of the House Subcommittee on International Organizations, revealed those "tentative findings" yesterday in announcing that the subcommittee would recommend a contempt citation against a Moon follower who has refused to answer questions about the Korean evengelist's tiest to the KCIA.

Fraser said the subcommittee had agreed to ask the International Relations Committee to bring a contempt charge against Daniel Fefferman, a leader in the Illinois branch of Moon's Unification Church, who was executive director of the National Prayer and Fast Committee, which Moon organized in 1974 to campaign in support of Nixon.

Fefferman has testified, under subpoena, twice in the past week before Fraser's subcommittee. Fraser said Fefferman had answered most questions put to him, but had refused to respond to "about a dozen" queries concerning the KCIA's involvement in the activities of the National Prayer and Fast Committee.

In announcing the contempt recommendation, Fraser released a report from the subcommittee's investigative staff stating that "we have received reliable information that [Moon] and organizasions connected with him maintained operational ties with the government of South Korea, and specifically the Korean Central Intelligence Agency."

Several sentences later, the release says that, in pursuing those ties, the subcommittee had focused on the activities of Moon's anti-impeachment committee.

The subcommittee report was the first formal government statement suggesting a link between Mooon the KCLA. Such a connection has been suggested numerous studies of Moon's church.

Links between the KCIA and Moon's anti-impeachment campaign were disclosed by The Washington Post last winter. The Post reported that Justice Department investigators had learned the KCIA had proposed the massive Capitol Hill demonstrations held by Moon's followers just before the House Judiciary Committee recommended Nixon's impeachment.

The Post said that Pak Bo Hi, Moon's chief aide and translator, was the connection between the Unification Church and the South Korean government. Pak reportedly has close ties with South Korean intelligence officials.

Pak and other church leaders have regularly denied any connection with the South Korean government. Moon has said that he is an agent of God and not of any temporal regime.

Fraser's subcommittee has received little of the attention that has been showered upon the House's other Korean investigation, being conducted by special counsel Leon Jaworski and the Committee on Standards of Official Conduct.

But Fraser unit has pushed doggedly for months in its probe of Moon's relationship with the alleged South Korean efforts to buy influence in the U. S. Congress.

Evidence of such activity could have serious financial implications for the Unification Church, which was has millions of dollars of real estate and business investments in the United States.

If the church were found to be engaged in "substantial" political or lobbying activity, it could lose the tax-exempt status granted to religious organizations.
