It's pretty clear to me he's used F&F as a means to promote his own career. I really don't think he's all that interested in the truth. He'll settle for something far less if he can advance his own ends.
I expect a degree of disingenuous behavior from any politician, Issa included. Any job that essentially requires you to be "what the people want" to be successful basically requires you to be something other than true to yourself. I don't really flinch at the grandstanding anymore. I just expect it.
