Quote: 

“Chelsea Bradley Manning has served a tough prison sentence, so the notion that the average person who is thinking about disclosing
vital classified information
would think that it goes unpunished, I don’t think would get that impression from the sentence that Chelsea Manning has served,” Obama said.

 
Citing the time served and saying Manning’s sentence was “disproportionate
,” Obama said: “It made sense to commute, and not pardon, her sentencing.”
