Target

Look, Rove's lawyer may say Rove isn't a target, but the prosecutor is telling him that he can't guarantee Rove won't be indicted at some later time - which means that he is warning Rove that his testimony could be used against him, something Fitzgerald hasn't done before.

The U.S. attorney's manual requires prosecutors not to bring witnesses before a grand jury if there is a possibility of future criminal charges unless they are notified in advance that their grand jury testimony can be used against them in a later indictment.

Rove has already made at least three grand jury appearances and his return at this late stage in the investigation is unusual.

The prosecutor did not give Rove similar warnings before his earlier grand jury appearances.
