They did indeed.
Senator Patrick Leahy, the ranking Democrat on the Senate Judiciary Committee, published this statement about Judge Roberts yesterday:
Although the Bush Administration still refuses to provide the most important examples of Judge Roberts’s policy views from his tenure as the politically appointed Principal Deputy Solicitor General, we have been able to review thousands of pages of documents that have been provided by the National Archives and Records Administration in response to earlier public requests.
Those papers that we have received paint a picture of John Roberts as an eager and aggressive advocate of policies that are deeply tinged with the ideology of the far right wing of his party then, and now. In influential White House and Department of Justice positions, John Roberts expressed views that were among the most radical being offered by a cadre intent on reversing decades of policies on civil rights, voting rights, women’s rights, privacy, and access to justice. [. . .]
The White House is steadfastly refusing to follow past precedent and allow Senators to review a good deal of the most relevant material from his work in the Executive Branch. By doing so they raise the inference that there is much to hide. They leave Judge Roberts with a heavier burden to carry during his upcoming hearings before the Judiciary Committee.
