Seriously: When did Kinder know that the Chiefs were lying?

This is what I learned about Lt. Governor Peter Kinder's day yesterday:

• He celebrated National Start Walking Day.
• He got a hug from Newt Gingrich.
• And somebody told Sen. Tim Green that Kinder was "not responsible for the KC Chiefs problem," no matter what the actual documents show or the MFDB's own counsel says.

But what I didn't learn is what actually happened. 

So when did Kinder know that the Chiefs were lying? And what did he do (or not do) to address (or enable) the dishonesty?
