The Supreme Court made the decision on Friday to withhold a large portion of documents pertaining to Supreme Court nominee Brett Kavanaugh’s service, to the horror of Senate Minority Leader Chuck Schumer. In a pair of tweets on Saturday, Schumer called the decision to withhold 100,000 pages a “Friday night document massacre,” noting that “President Trump’s decision to step in at the last moment and hide 100,000 pages of Judge Kavanaugh’s records from the American public is not only unprecedented in the history of Supreme Court nominations, it has all the makings of a cover up.”

He accused the president and Republican leaders of trying to hide the apparent cover-up at the start of a holiday weekend.

Both the White House and the Department of Justice have determined that the withheld portion of Kavanaugh’s documents are protected by constitutional privilege, according to a letter from lawyer William Burck to the Senate Judiciary Committee, via CNN.

Former president George W. Bush charged Burck with reviewing the presidential library’s portion of the documents, and Burck explained in the letter that Bush had directed him to “err as much as appropriate on the side of transparency and disclosure.” Of the just under 664,000 pages, Burck said he gave the committee “every reviewable” document except those “presidential records protected by constitutional privilege.” Democratic senators argue that, the 100,000 withheld pages have to do with Kavanaugh’s tenure as White House staff secretary from 2003 to 2006.
