Scott McClellan finally got asked the 5th amendment question this afternoon with respect to the Plame investigation.

He said that he had "no knowledge" of anyone taking the 5th.

He said he checked with the Counsel's office too; and their response was apparently the same, i.e., no knowledge.

I'm told part two of the question (i.e., whether President Bush's order of cooperation would be consistent with members of his staff taking the fifth) got asked in some form. And McClellan's response was simply to restate in general terms the president's "policy" that everyone should cooperate with the investigation.

We'll bring you more details later.
