I will be the first to admit it sounded like he confirmed his father said this - but I honestly believe what he was trying to point out is that IF he told someone or anyone to do something (Comey or anyone) it would not be "I hope" - it would be very direct.  Point being saying his father would never speak in such soft language so Comey saying he used the term "I hope" showed it was made up...  I am sure it will get pounced on and that is why you have to be careful of every word you choose in todays hyper sensitive world...
