I'm going to say this again, perhaps you will read and understand it this time?

In order for an obstruction of justice crime to be committed, there doesn't have to be an investigation against the person who committed the obstruction. Endeavoring to interfere or influence any investigation of anyone (and especially using the power of his office to do so) is obstruction of justice. Now, is there anything about this that you still. don't understand?

Comey, who served multiple Presidents from both parties, a law enforcement professional testifying under oath, can't be trusted? But a man who is proven to be lying the majority of time he opens his mouth, can? You're going to have to find someone way more naive and gullible than me to try to sell that load of manure.
