Gonzales; Senate testimony

If all Alberto Gonzales is going to do is tell the truth, then what's all the fuss?

Attorney General Alberto Gonzales has virtually wiped his public schedule clean to bone up for his long-awaited April 17 testimony before the Senate Judiciary Committee—a session widely seen as a crucial test as to whether he will survive the U.S. attorney mess.

At a recent "prep" for a prospective Sunday talk-show interview, Gonzales's performance was so poor that top aides scrapped any live appearances.

What kind of "prep" do you need to tell the truth under oath? There is the truth, and then there is not the truth. If you know the difference, and are determined to tell the truth, what's the problem?
