Update: Matt Apuzzo of the Associated Press reports:

Defense attorneys could read them as a hopeful sign if they suggest the entire jury is confused, but prosecutors might see them as an opportunity to clarify something for a lone holdout juror.

There was a single jury instruction for counts 2 and 3 on the false statement charges pertaining to Tim Russert (Count 2) and Matthew Cooper (Count 3.) I've culled out the language pertaining only to Count 3.

The confusion seems to be over this part:

Count three of the indictment alleges that Mr. Libby falsely told the FBI on October 14 or November 16, 2003, that during a conversation with Matthew Cooper of Time magazine on July 12, 2003, Mr. Libby told Mr. Cooper that reporters were telling the administration that Mr. Wilson’s wife worked for the CIA, but that Mr. Libby did not know if this was true.

Update: As I say in the comments below, I think there is a good chance of a verdict today. I suspect the jury has decided counts 1, 2, 4 and 5 and is only still struggling with Count 3.

When their first substantive questions began coming in, I speculated they would start with count 1, realize they had to decide counts 4 and 5 (perjury to grand jury) to resolve it, and finish with counts 2 and 3. I still think that's what they are doing, although this is more tea leaves.
