The House yesterday stood by the Reagan administration's request for $500 million in emergency aid to Egypt, voting 314 to 110 against an amendment to a supplemental spending bill for the rest of 1985 that would have eliminated the economic assistance.

At the same time, the House gave tacit approval to the administration's request for $1.5 billion in emergency aid to Israel to help its flagging economy. No amendments were offered to delete the Israel aid.

The emergency aid would be on top of $2.2 billion Congress approved already this year for Egypt and $2.6 billion for Israel.

The action came as the House wrapped up action on most of the $13.4 billion supplemental money bill, brushing aside GOP-sponsored amendments to reduce funding levels in the bill. Only aid to Nicaraguan counterrevolutionaries and a final vote on the overall bill were left to be decided today.

Rep. Hank Brown (R-Colo.) offered the amendment yesterday to delete the money for Egypt. He said that in a time of high deficits, when other programs are being frozen by Congress, "to give Egypt $500 million . . . is simply unacceptable."

In addition, he said, Egypt had failed to live up to all the terms of the Camp David peace accords with Israel and often voted against the United States at the United Nations.

But a broad group of Democrats and Republicans defended the administration's request. Rep. Jack Kemp (R-N.Y.) said, "Egypt has been a very moderating nation" despite its failures to live up to the accords, and it should be encouraged.
