Sen. Paul S. Trible (R-Va.), who amassed a $1.9 million political war chest before deciding not to seek reelection this year, will give his campaign contributors refunds of 60 cents on the dollar by April 1, a Trible spokesman said yesterday.

But an aide to J. Marshall Coleman, a potential Trible rival for the Republican gubernatorial nomination, charged that Trible is taking too long to return the money and may be shortchanging his contributors as well.

Dennis Peterson, director of Coleman's campaign committee, said yesterday that the Trible campaign continued to spend money on travel and entertainment for several months after Trible announced his withdrawal from the Senate race Sept. 19.

Peterson was particularly critical of a $3,400 restaurant bill that was run up on Dec. 11.

"I believe {Trible's} contributors would not be pleased to see their money spent in these ways," Peterson said. "He has an obligation to return as much money as possible.

John Miller, a Trible spokesman, said that all contributors who asked for refunds have been sent half of their money back, and that they will get another 10 cents on the dollar before the campaign closes its books in two months.

When Trible withdrew, he said that he would relinquish all campaign funds that were left over after expenses. He said that creditors would be allowed to choose whether the money would be sent back, given to the Republican Party or donated to charity.

Miller said that the $3,400 luncheon in December was for a group of Trible contributors who had been told they would have a chance to meet with the senator. He said that campaign officials feel they are handling the money properly.

According to a campaign spending report that U.S. Senate officials released yesterday, the Trible campaign refunded more than $565,000 during the second half of last year.

On Jan. 1, the campaign still had about $537,000 in the bank.

When Trible withdrew, several prominent Republicans pressured Trible to give up his campaign war chest. Several state legislators are organizing to draft Trible into the governor's race.
