So is she going to be the sacrificial goat for the Slimes or was she implicated in testimony behind the locked doors.
Maybe she can provide testimony about how often, if ever, Plame served as a source to reporters on the subject of WMD and maybe she can testify to how well known Plame's affiliation with the CIA was known. And maybe she can testify if the Wilsons tried to peddle to her their false story about Niger and Joe Wilson "debunking" the SOTU yellowcake story (an outrageous misrepresentatoin of the scope and findings of his tea-sipping journey).
In other words, just because a reporter is called, in my theory, does not mean they engaged in wrong-doing. It may be they are called to provide information about others...like the Wilsons and their cohorts in this plot to bring down a president.
