President Nixon's special adviser on campus unrest denied Wednesday that he had told Nixon that Berkeley and Columbia had been destroyed by student unrest.

A report broadcast Tuesday by NBC had indicated that G. Alexander Heard, chancellor of Vanderbilt University, would tell the President that neither school would be able to function next year because of student unrest and that he would blame Vice-President Agnew's rhetoric for much of the unrest.

Heard refused to comment on this report specifically on Wednesday, saying only that he had named "no specific institutions." He also refused to comment on a report that he had asked the President to step in with "emergency diplomacy" to relieve an "academic crisis."

Heard said he had called officials at Columbia and Berkeley to assure them that he would not name the two schools in his report.

Heard made the statement at a press briefing following a meeting with Nixon. Also present at the meeting were James E. Cheek, president of Howard University, who advises Nixon on problems at black universities, and John H. Finch, former Secretary of HEW and now special counsel to the President.

Heard said he would make a public statement next week, when he finished his tour as campus adviser to the President.

Frank Jordan, NBC Washington Bureau chiof, said the network would stand by the report.
