That person will probably claim that they heard it from the boss (why else put their own head on the chopping block if it didn't?), so diarise it anyway - it's all ammunition and they are just handing it over to you. Too easy.
In the words of the awesome people who helped me in my case with a man driven by ego, "give him enough rope". Really, he's bringing the rope and giving himself plenty for this metaphoric hanging.
This pretty much says it - give him enough rope ....
