Sure.
To start with, take a look at that first clause: "The man who admitted leaking classified documents..." The framing of this is right off the bat aggressive, casting him in the light of a criminal. Were CNN to want to cast him in a positive light they could have chosen to write it something like this: "The man who exposed widespread secret surveillance of American's electronic communications..." Instead CNN chose to emphasize the criminal aspect, rather than the civil liberties/anti-democratic aspect.
Next: "... purportedly went online..." The use of the word "purportedly" here is interesting. Why is that questioned? To associate doubt with him. It's subtle, but nevertheless there it is.
Next: "declare the truth would come out even if he is jailed or killed". Out of all the questions which were answered CNN focused on this one because it most easily supports the "egotistical" narrative they are attempting to paint him with. Implication: "He is setting himself up as some kind of martyr! How arrogant!"
Next: "Obama did not fulfill his promises and expanded several 'abusive' national security initiatives." This one is, to me, the most blatant. The scare quotes around "abusive" are of course the most obvious. But look how the frame it: "national security initiatives". Not "domestic spying programs", or "electronic surveillance mechanisms", or something else. After all, no one who calls themselves reasonable can be opposed to national security!
It's subtle, and of course debatable. But it's certainly present. CNN has their own slant, and it is obviously pro-NSA.
Also note that nowhere to they actually link to the Q&A page.
Let's rewrite it, communicate the same information, but make it skeptical towards the NSA:
"Edward Snowden, the former NSA contractor who exposed widespread secret surveillance of American's electronic communications and online activities, did an online question-and-answer session today, making himself available to provide follow-up answers to questions raised by concerned citizens over the reach and power of the notoriously secretive intelligence agency."
