The Empty Wheel has a list of "potential witnesses and names that may be mentioned during the trial". Most are reporters, lawyers, or government officials with a clear (or easily imagined) connection to the case.
However, what are Donald Fierce, "Government relations consultant" and Richard Hohlt, "consultant", doing on the list? Mr. Hohlt is a big Republican donor and lobbyist who works for "banking and manufacturing interests"; Mr. Fierce is a lobbyist and former member (1993-95) of the Republican National Committee.
I welcome more background and speculation - the current theory is that one or both of these chaps may have learned about Ms. Wilson's CIA affiliation prior to the Novak column in the course of their big-time Washington moving and shaking.
MUCH LATER: Eventually. Bob Novak testifies - he gave a copy of his column to Hohlt on July 11 after he finished it; Hohlt them sent a copy to Rove.
