It doesn't sound like they got Ashcroft fully on board:

What is known is that in early 2004, about the time of the hospital visit, the White House suspended parts of the program for several months and moved ahead with more stringent requirements on the security agency on how the program was used, in part to guard against abuses. The concerns within the Justice Department appear to have led, at least in part, to the decision to suspend and revamp the program, officials said. The Justice Department then oversaw a secret audit of the surveillance program.

More big news: In 2002, even then Deputy AG Larry Thompson was kept in the dark.

At its outset in 2002, the surveillance operation was so highly classified that even Larry Thompson, the deputy attorney general to Mr. Ashcroft, who was active in most of the government's most classified counterterrorism operations, was not given access to the program.

That led to uncertainties about the chain of command in overseeing law enforcement activities connected to the program, officials said, and it appears to have spurred concerns within the Justice Department over its use. Mr. Thompson's successor, Mr. Comey, was eventually authorized to take part in the program and to review intelligence material that grew out of it, and officials said he played a part in overseeing the reforms that were put in place in 2004.

It sounds like some former Justice Department lawyers or lawyers in the White House Counsel's office believe Bush's warrantless spying plan was illegal and are talking. I doubt it's anyone high up like Comey or Thompson, who don't talk out of school, but those in the middle ranks. It's time for a special counsel to be appointed.
