The subpoenas seek records, including expense documents, and indicate that the investigation by Attorney General Tom Corbett known as "Bonusgate" is far from over as it enters its second year.

Spokesmen for Democrats and Republicans in the House confirmed yesterday that both caucuses received recent subpoenas.

"As we've said repeatedly for the past several months, we are cooperating with every aspect of the attorney general's grand jury investigation," said Tom Andrews, press secretary to Majority Leader Bill DeWeese (D., Greene).

Said Steve Miskin, spokesman for the House Republicans: "We intend to continue to fully cooperate with this investigation. We are not throwing up any roadblocks."

Miskin and Andrews refused to discuss details of the subpoenas. But sources have confirmed that some of the expenses sought by the grand jury were paid through special discretionary accounts controlled by legislative leaders and long derided by critics as unchecked slush funds.

Over the years, leaders tapped those accounts for such things as meals, consultants, polling, plane trips, and gifts to staffers.

Kevin Harley, Corbett's press secretary, would not comment on the latest subpoenas, citing grand jury secrecy rules.

So far, the investigation has focused mostly on Democrats in the House, who handed out the most in bonuses.

At the end of 2006, after winning back control of the lower chamber, Democrats gave nearly $1.9 million to 717 aides. At least 15 caucus staffers have been called to testify before the grand jury, and attorney general's agents last year seized 20 boxes of records from Democratic research offices in the Capitol.

In November, DeWeese forced seven aides from their jobs after discovering what he later described as damning e-mails that allegedly tied some bonuses to campaign work.

DeWeese has repeatedly said that he was unaware of the extent of the bonuses and had delegated them to others.

House Republicans, who gave $270,000 to 45 aides in 2006, first received subpoenas for personnel records in October. Just last month, the grand jury subpoenaed records from Republicans in the Senate. The caucus had given bonuses totaling $180,000 to 16 workers.

Democrats in the Senate, who awarded the least in bonuses - $38,000 to a dozen staffers in 2006 - have not received any subpoenas, said C.J. Hafner, the caucus' chief counsel.
