The 43-page federal indictment alleges a number of cases and times where thousands of dollars in gifts and loans were given to the former Governor and First Lady, but motions filed by McDonnell's defense attorneys argue the indictment is too vague and doesn't show specifically any times the governor used his office or officially tried to help Williams.
Legal expert Russ Stone says the motion is a good indication of how the defense plans to argue the case in court, saying it also sends a message to the judge.
"Clearly what they're trying to nail the government down into saying is exactly what official act. Do you claim Governor McDonnell did in order to justify the 'bribes' that he's alleged to have received?" he says. "They're trying to make it clear that this is, this is where we're going with the defense and this is what we're going to be arguing and this is what we want you looking at as you hear the evidence as it comes in."
Meanwhile federal prosecutors argue the indictment shows McDonnell what he's accused of doing and gives him more than enough to prepare a solid defense.
"Our 43-page indictment goes into fairly great detail of what we have accused him of doing. We think that's more than adequate."
Stone says ultimately the case will come down to whether prosecutors can prove McDonnell used his office to try and help Star Scientific.
