The chairman of the House Permanent Select Committee on Intelligence said yesterday that he decided to postpone voting on the CIA's covert action budget for fiscal 1991 without any urging from President Bush or other administration officials.

The chairman, Rep. Anthony C. Beilenson (D-Calif.), said he and the committee's ranking minority member, Rep. Henry J. Hyde (R-Ill.), agreed "between us" to delay voting on the covert aid portion of the intelligence budget until September because of current U.S. negotiations with the Soviet Union on the war in Afghanistan and on other trouble spots in the world.

The Washington Post reported Saturday that Beilenson had announced the postponement at last week's session of the House intelligence budget subcommittee, which Beilenson also heads. Sources told The Post that Bush had sought the delay and that Beilenson agreed to it after a telephone call from the White House. Beilenson said this was incorrect.

"I said the administration would probably be happy" because it provided more time for the negotiations, Beilenson said. But he added, "The president didn't call me, nor did anyone else from the administration."

Covert aid to antigovernment forces in Afghanistan, Cambodia and Angola is becoming an increasingly contentious issue between Congress and the administration.

Beilenson said he also felt that a delay until September "would not prejudice any efforts by people {on his committee} who might want to try to reduce the amounts" in the covert action budget.

The administration has been seeking about $50 million in military aid for Jonas Savimbi's rebel army, UNITA, in Angola, and about $10 million in covert military training and supplies for the noncommunist resistance forces in Cambodia, according to informed sources. Afghanistan aid reportedly is costing between $300 million and $400 million in fiscal 1990.

Hyde could not be reached for comment.
