Senate Republicans have requested information about Attorney General nominee Eric Holder’s role in the Elian Gonzalez controversy as part of a broad probe into his tenure with the Clinton administration and potential ties to presidential scandals during that era.

Eight of nine GOP members on the Senate Judiciary Committee wrote Clinton Presidential Library Director Terry Garner on Thursday to ask for 10 categories of material, and that includes any information on Holder’s involvement with the Cuban boy seized by U.S. agents in April 2000.

Seeking information about Gonzalez suggests Republicans are seeking issues that will resonate outside the Beltway, unlike the Rich pardon.

An aide to Judiciary Committee Chairman Patrick Leahy (D-Vt.) says Republicans never showed the Clinton Library letter to Leahy but simply began referring to it in comments on the Senate floor on Thursday. The aide also said Republicans are being hypocritical by asking for a voluminous amount of information about an attorney general candidate.

“They’re applying a standard of Supreme Court nominees to an attorney general nominee,” the aide said. “Not to diminish the importance of the office, but this is not a lifetime appointment to the Supreme Court like (Samuel) Alito or (John) Roberts. It seems the hypocrisy here might be in their direction.”

Under pressure from Republicans on the committee, Leahy on Monday rescheduled Holder’s confirmation hearings from Jan. 8 to Jan. 15, five days before Obama’s inauguration.

In a separate letter to current Attorney General Michael Mukasey, the senators ask for information tying Holder to 17 separate issues including the Rich pardon and the Gonzales case, but also Vice President Al Gore’s 1996 fundraising scandal and Clinton’s history of special prosecutors in the Whitewater and Monica Lewinsky scandals from 1993 to 2001.

The letters were signed by GOP committee members Arlen Specter of Pennsylvania, Sam Brownback of Kansas, John Cornyn of Texas, Tom Coburn of Oklahoma, Chuck Grassley of Iowa, Orrin Hatch of Utah, Lindsey Graham of South Carolina and Jon Kyl of Arizona. Only Sen. Jeff Sessions (R-Ala.), a former U.S. attorney, did not sign either letter. A Sessions spokesman did not immediately return a call for comment.

The senators also asked for any Holder ties to pardons of 16 Puerto Rican nationalists granted by President Clinton in 1999, as well as a gun-control measure Clinton signed that year and the extension of the gun-control Brady Bill.

The Rich pardon remains a focus of sorts, along with others Clinton granted on his final day in office on Jan. 20, 2001, including Rich’s partner, Pincus Green. The senators asked for “any clemency or non-clemency related matter” regarding six final-day pardons, including those of Rich and Green, as well as any communication involving the Rich and Green pardons between Holder and the U.S. Attorney’s office for the Southern District of New York.
