Newsweek's Michael Isikoff's take is here.
It is extremely rare, if not unprecedented, for Cheney's own notes to be made public. The notes--apparently obtained as a result of a grand jury subpoena--would appear to make Cheney an even more central witness than had been previously thought in the criminal probe.
....Fitzgerald first alleged that Cheney had questioned whether Wilson's trip was a "junket" in a court filing last month. In that filing, Fitzgerald also asserted that the vice president, acting with the approval of President Bush, had authorized Libby to disclose portions of the classified National Intelligence Estimate on Iraq to rebut some of Wilson's claims.
....Fitzgerald in his court filing indicated he plans to introduce a copy of Cheney's annotated version of the Wilson column to show the vice president's interest in the circumstances surrounding Wilson's trip was an important matter to Libby that week and explains many of his actions.
Here's another nuggat from the Friday filing: Fitz is going to introduce the Novak column outing Valerie Plame. Isikoff writes:
Fitzgerald said he will do so in order to introduce evidence about a series of conversations that he argued could undercut one of Libby's principal defenses: that he had no reason to believe Plame's employment was a sensitive matter and therefore had no reason to lie to the grand jury about when and with whom he spoke about it.
According to Fitzgerald's filing, on the day that the Novak column was published, a CIA official was asked in Libby's presence by another Cheney aide whether he had read the column. The CIA official had not. But shortly thereafter, the unidentified CIA official discussed in Libby's presence "the dangers posed by disclosure of the CIA affiliation of one of its employee as had occurred in the Novak column," Fitzgerald wrote.
....Fitzgerald asserts, "the evidence about the conversation concerning the Novak column provides a strong motive for the defendant to provide false information and testimony about his disclosures to reporters."
The May 5 Libby hearing transcript is still generating great analysis. Christy of Firedoglake weighs in here and here . Empty Wheel includes her thoughts in her post today about Cheney. Tom Maguire also has a detailed analysis.
