An article from July 15th and the Book, The Dark Side (Spying and Democrats)

As we witness not just Republicans, but also Democrats in Congress, acting repeatedly to immunize executive branch lawbreaking and to obstruct investigations, it's vital to keep that fact in mind. With regard to illegal Bush programs of torture and eavesdropping, key Congressional Democrats were contemporaneously briefed on what the administration was doing (albeit, in fairness, often in unspecific ways). The fact that they did nothing to stop that illegality, and often explicitly approved of it, obviously incentivizes them to block any investigations or judicial proceedings into those illegal programs.

Identically, numerous key Democrats in Congress -- including Rockefeller and Harman -- were told that Bush had ordered the NSA to spy on American without warrants and outside of FISA. None of them did anything to stop it. In fact, while Rockefeller wrote a sad, hostage-like, handwritten letter to Dick Cheney in 2003 (which he sent to nobody else) -- assuring Cheney that he would keep the letter locked away "to ensure that I have a record of this communication" -- Harman was a vocal supporter of the illegal NSA program. Here's what she told Time in January, 2006 in the wake of the NYT article revealing the NSA program:

Some key Democrats even defend it. Says California's Jane Harman, ranking Democrat on the House Intelligence Committee: "I believe the program is essential to U.S. national security and that its disclosure has damaged critical intelligence capabilities."

Harman then went on Fox News and pronounced that the NSA program was "legal and necessary" and proudly said: "I support the program." Even worse, in February, 2006, Harman went on "Meet the Press" and strongly suggested that the New York Times should be criminally prosecuted for having reported on the illegal program. And indeed, in 2004, Harman demanded that the NYT's Eric Lichtblau not write about the NSA program.
