His voice bristling over the long-distance line from Seoul. "Catholic Father" had some harsh words about the work of "Dr. Hamilton" in Washington.

"Dr. Hamilton" had already received three "units of cloth" for his work on Operation White Snow. "Catholic Father" pointed out. Now the "Patriarch" wanted results, Specifically, "Dr. Hamilton" was to see to it that, during the next congressional debate on foreign aid, any critical views about South Korea or its government would be suppressed.

That encoded 1974 telephone conversation, in which the views of South Korean President Park Chung Hee ("Patriarch") were relayed by the director at the Korean Central Intelligence Agency ("Catholic Father") to a KCIA agent here who was working with businessman Hancho Kim ("Dr Hamilton"), was described in testimony yesterday as the House Committee on Standards of Official Conduct heard new details about the Korean influence buying program.

American currency dispatched for use in entertaining congressmen was to be called "cloth," with one "unit of cloth" equal to $100.000.

In his second day before the committe, Kim Sang Kuen, a former KCIA agent attached to the Korean embassy here, told the committee about the operations of Hancho Kim and Tongsun Park, two businessmen who have been indicted on charges of conspiring to bribe members of Congress and of being Korean agents.

The witness, who defected from the South Korean embassy in 1976, also described the Korean government's complicated plans to conceal its links to the two businessmen.

Kim Sang Kuen told the House committee that the Koreans even had code names for American officials, including a group of about five congressmen predominantly Republicans, who were called the "advance guard." Kim Sang Kuen said this was a group with whom Hancho Kim claimed to have close ties.

Under the committee's ground rules for the hearing neither the "advance guard" nor other member of Congress or executive officials alluded to in the testimony were identitied. The commitee lfulicated that the involvement of individual Americans might be reviewed at later hearings.

The sole exception came when another witness. B.Y. Lee a former assistant to Tongsun Park here, inadvertently told the committee about a visit to the office of former Rep. Otto Passman (D-La) in 1976.

Lee said he carried a sealed envelope from Tongsun Park to Passman, and received from the congressman a gold pocket watch for delivery to Tongsun Park. Jeffrey Harris, an attorney on the committee staff, said this transaction "looked like it was simply the purchase of a watch."

Kim Sang Keun and B.Y. Lee mainly discussed two similar KCIA projects - operation White Snow, involving Hancho Kim, and Operation Ice Mountain, involving Tongsun Park - that were designed, as Kim Sang Keun explained, to win support for South Korea among American congreessmen, government officials, academicians and journalists.

Most of yesterday's testimony involved various efforts to win friends in Congress. But there was also a reference to Korean contacts with members of Gerald R. Ford's White House staff.

In answers to questions from the committee, Kim Sang Keun related a conversation in April, 1975, in which Hancho Kim had said that he needed funds for two assistants to then-President Ford.

That assertion came at a time when Hancho Kim was seeking additional money from the KCIA for his White Snow program, Kim Sang Keun explained. The witness said he had no evidence of White House contacts other than Hancho Kim's comments.

It has been reported that some officials from the Ford White House staff had social contacts with Tongsun Park. There has been no previous mention of White House contacts with Hancho Kim.

In addition to this White House connection, Kim Sang Keun said, Hancho Kim reported to the KCIA that he was continually in contact with members of Congress. Hancho Kim Said he regularly entertained the members at the Sans Souci restaurant in Washington and at his home in Prince George's County.

Kim Sang Keun related a report sent to the KCIA in which Hancho Kim said that he and Tongsun Park were in contact with 40 or 50 members of Congress.

The only clear statement of what the two businessmen were meant to achieve was the 1974 telephone call from the KCIA director, code-named "Catholic Father," in which the director said, according to the testimony, that Hancho Kim "should arrange that any critical views in the Congress should be suppressed" during an upcoming foreign aid debate.

Kim Sang Keun said he relayed that order to Hancho Kim, who said he would carry it out.

Kim Sang Keun testified under heavy guard yesterday, with two U.S. marshals continuously at his side. For security reasons, he insisted that television and still cameras not be used during his testimony.

Because Kim Sang Keun spoke English through an interpreter, and because the committee counsel, Thomas Fortuin, posed scores of precise questions to him, the testimony moved slowly. That together with Kim Sang Keun's failure to provide specific answers to most questions, left the committee members visibly exasperated.

Moreover, little of Kim Sang Keun's testimony was based on his personal knowledge; he was generally relating what someone elase had told him.

At one point discussing an alleged $20,000 gift from Hahn Pyong Choon, a former Korean ambassador here, to a congressman, the witness told the committee that Hancho Kim told him that the congresman told him that the ambassador told him that he would provide the money.

In addition to the two Koreans, the committee heard briefly from two congressmen's wives.

The wives of Reps. Kika de la Garza (D-tex.) and John T. Myers (R-Ind.) both told how they were offered envelopes stuffed with U.S. currency during a visit to Korean in 1975.

Mrs. de la Garza said the woman who offered her the cash was Mrs. Kim Dong Jo, wife of the Korean ambassador to the United States from 1967 to 1973. Mrs. Myers could not identify the woman who offered her cash on the same evening.

Both women said their husbands returned the money to Korean authorities.

In testimony Wednesday, the committee heard that Kim Donlerg Jo, while ambassador here, persoally made trips to Capitol Hill to distribute envelopes stuffed with cash.
