From a July 2002 Bush Press Conference, when GWB was asked about the topic of the recklessness and the re-regulation of the 1990s:

Q. Sir, you said in your speech tomorrow you’re going to talk about some of the excesses of the 1990’s when a lot of money was flying around people were playing a lot of games … money. You weren’t president then. Bill Clinton was president. Do you think in some way he contributed to that? Set a moral tone in any way?
A: No.
