"How, commission officials demanded to know, could the White House deny a federal panel investigating the worst crime in U.S. history access to documents that it had already shared with a journalist?

“Woodward was a point of reference to show the PDBs were not as sacrosanct as they claimed,” said one commission official familiar with the negotiations with the White House. “In his book, Woodward claims he saw the PDBs. That was an argument that these were not the ‘Holy of Holies.’”

Ya gotta admit, this is funny. And scary."

Yes, I must admit that it is funny that you think this article is scary.
Btw, what exactly do you find scary- the power of Congress to compromise the function of the executive branch? Somehow, I can't imagine this would be your concern.
Or was the phrase "executive privilege"? Is that what's scary?
Do you have any idea what "executive privilege" means? [clue: it has nothing to do with bathroom keys or parking spots].
