Virginia Republican officials have delayed a reception and dinner, originally scheduled for tomorrow, to raise funds for the new Rirchard D. Obenshain Center here in hopes of having a bigger impact on the November elections.

The fundraiser, according to GOP officials, will be rescheduled for September to coincide with the opening of the center. Obenshain, a former state Republican Party chairman, was killed Aug. 2, 1978, in a plane crash while campaigning for the U.S. Senate. Republicans subsequently picked John Warner as the party nominee, who won the Senate seat that fall.

The guest speaker for the dinner, scheduled for the Richmond Coliseum, was to have been former secretary of state Henry A. Kissinger.

In announcing the postponement, Louis Williams, chairman of the Obenshain Foundation said it is hoped Kissinger will be able to attend the fall ceremonies.

Added a state GOP official, "It was felt that we could get the maximum positive effect from an appearance of the former secretary of state if we had him come at the beginning of the big campaign push. Any statements he might have would have more impact for November at that time."

The center will serve as the GOP's new state headquarters. Jeff Gregson, executive chairman of the state party, said refunds will be made to everyone who had a reservation for the event.
