Kavanaugh's file boxes also include grand jury testimony by White House counsel Bernard Nussbaum about a call from Clinton adviser Susan Thomases on the day after Foster's death. The transcript was withheld from public release due to grand jury secrecy rules, but the call was the focus of inquiries by congressional Republicans about whether it prompted the White House to resist law enforcement efforts to search Foster's office.
A broader index of Kavanaugh's files shows still-unreleased folders containing memos on "perjury (obstruction/false statements)," shredding of records by Hillary Clinton's former law firm, impeachment, grand jury secrecy issues related to President Bill Clinton's interview about Foster's death, and a conspiracy theory at the time known as the INSLAW Affair.
