As he nears the end of his cross-examination -- "Just a few more questions," he's said more than once -- Sam Adam has begun to question the credibility and intentions of government witness John Harris.

Adam questioned Harris about his plea deal with prosecutors, under which a sentence that might have been 20 year in prison and a $250,000 fine will be reduced due to his cooperation.

And he called into question the witness' ability to testify about what the ex--governor meant when he is heard speaking on government wiretaps.

"Would you agree that the best person to say what the governor was thinking would be the governor himself?" Adam asked him.

"I can't speak to what he was thinking, necessarily, but what I underand based on my years working for him and the amount of contact we had," Harris said calmly.

Adam has wrapped up his cross-examination and prosecutor Carrie Hamilton is re-directing.
