That's not what's being "reported" though. What's being reported is that "Trump promised a pardon if Assange says it's not from Russia". Notice how Russia or promise of a pardon does not come up in your Rohrabacher quote (which, BTW, I'd need to verify as well before I believe it). It's like I said "I'll call on Jeff Bezos to give you a million dollars if you vote in this election", without even specifying who I want you to vote for.
