The article isn't online yet, but Justin Logan finds a startling (well, maybe not startling anymore) excerpt from a piece in the most recent American Conservative:
On Sept. 28, at the Vice President's request, the Agency provided a special briefing on the subject of Jordanian terrorist Mu'sab al-Zarqawi. The CIA's Counter Terrorism Center (CTC) reviewed all of the available intelligence on the subject and based its briefing on a just completed comprehensive intelligence analysis. The CTC concluded that Saddam Hussein had not materially supported Zarqawi before the U.S.-led invasion and that Zarqawi's infrastructure in Iraq before the war was confined to the northern no-fly zones of Kurdistan, beyond Baghdad's reach. Cheney reacted with fury, screaming at the briefer that CIA was trying to get John Kerry elected by contradicting the president's stance that Saddam had supported terrorism and therefore needed to be overthrown. The hapless briefer was shaken by the vice president's outburst, and the incident was reported back to Goss, who indicated that he was reluctant to confront the vice president's staff regarding it.
Caveat: At least as far as I can tell from what's at Logan's site, the anecdote's not sourced. Ingest as much sodium chloride as seems appropriate.
