The Washington Post reports today that Lewis Libby’s defense team has taken the obvious step of trying to force the prosecution to disclose the factual circumstances of Valerie Plame’s employment:

Attorneys for Vice President Cheney’s former chief of staff urged a court yesterday to force a prosecutor to turn over CIA records indicating whether former CIA operative Valerie Plame’s employment was classified, saying the answer is not yet clear.

As we have previously discussed here and here, it seems unlikely, on the basis of what we know, that Valerie Plame really was employed as a covert operative in the sense refered to in the 1982 Intelligence Identities Protection Act.
