Six Democrats on the Senate Judiciary Committee sued the National Archives to gain access to documents related to Supreme Court nominee Brett Kavanaugh’s time in the George W. Bush administration, according to a report on Monday.

The senators – Cory Booker, Richard Blumenthal, Patrick Leahy, Sheldon Whitehouse, Mazie Hirono and Kamala Harris – want the federal court to order the release of the records immediately, The Hill reported.

“The Senate and the American public have a brief opportunity to sift the record of Judge Kavanaugh’s public career before the Senate is expected to make an effectively irreversible decision that would shape the federal judiciary for decades, and the individual Senators have a unique platform to probe and publicize Judge Kavanaugh’s record,” lawyers for the senators at the watchdog group American Oversight wrote in the suit filed in US District Court in the District of Columbia.

The suit combines three requests that Democrats on the committee submitted in August to the National Archives, the CIA and the Bush library for documents relating to the six years Kavanaugh spent at the Bush White House as senior associate counsel and staff secretary to the president.

The requests were made through the Freedom of Information Act, which gives agencies up to 20 days to approve or deny a request and 10 days to decide on a request for an expedited process.

The 10 Democrats on the Judiciary Committee also on Monday sent a letter to Sen. Chuck Grassley, the chair of the panel, asking him to delay a Thursday confirmation vote for Kavanaugh after a California professor claimed in a Washington Post story on Sunday that Kavanaugh sexually attacked her in 1982 during a high school party.

Christine Blasey Ford told the newspaper that Kavanaugh and another man – both “stumbling drunk” – took her to a bedroom where Kavanaugh pinned her down on the bed, groped her and prevented her from calling out for help.

Kavanaugh has denied the charges.
