Attorney General Griffin B. Bell has disputed a Washington Post report that he told President Carter he expects the indictment of several present and former congressmen in connection with the investigation of South Korean influence-buying on Capitol Hill.

Characterizing the story, Published in Thursday's editions of The Post, as "extreme distortion," Bell issued a written statement that said, "there are many assertions in the article, attributed to unnamed sources, that are totally inaccurate, misleading and damaging to the investigation."

Bell's spokesman refused to identify any such inaccuracies, however.

According to a source close to Bell, he is upset over the statement that he told Carter he expects the indictment of several present and former congresmen. Bell is adamant, the source said, that he did not make any prediction to Carter.

A knowledgeable source indicated yesterday however that after the briefing by Bell Carter had the impression that the indictments are to be expected.

Justice Department sources familiar with the investigaiton said they understoon that Bell had fully brifed the President on the general dimensions of the probe.

"Any one familiar with the facts would logically conclude that . . . while no firm decisions have been made . . . several (present and former congressmen) are going to be indicted," one source said.

An aide to Bell stressed that the only expectation Bell left Carter with was that the investigation would be concluded as quickly as possible. The aide said Bell did not intend to curtail the probe or to end it prematurely, but that he probably would assign additional manpower to speed it up.
