Senate Judiciary Chairman Patrick Leahy strongly rebuked Republicans for demanding that the National Archives turn over additional documents on Supreme Court nominee Elena Kagan, accusing them of “using double standards in connection with this nomination.”

Judiciary ranking member Jeff Sessions (R-Ala.) had asked the Vermont Democrat earlier this week to help facilitate the release of more documents.

But on Thursday, Leahy said he wouldn’t heed Sessions’ request. He said in a written response to Sessions: “You now seek to continue to search for additional documents [that are] not likely to aid in our consideration of the nomination.”

Leahy also accused Republicans of using a double standard in asking for the additional paperwork. Leahy noted that in the lead-up to the confirmation hearings of Chief Justice John Roberts, Republicans did not assist Democrats who were trying to secure more documents.

“In 2005, in connection with the Roberts nomination, we were limited to Reagan Library documents on selected topics. I recall that no Republican joined that request, nor did any Republican protest when it was not timely fulfilled. Further, no Republican Senator complained about documents withheld on personal privacy grounds,” Leahy wrote.

“I do not think we should be using double standards in connection with this nomination,” he added.
