A journolist may not injure a Democratic politician or, through inaction, allow a Democratic poitician to come to harm.
A journolist must obey the orders given to it by Democratic politicians, except where such orders would conflict with the First Law.
A journolist must act like a journalist as long as such deception does not conflict with the First or Second Law.

Thank you!
Not taking it far enough. I like the idea some German politicians have been throwing around (and the plenty of the media there ignored).
See, in order to make sure only officially labeled journalists get to do things, we must restrict access to these thing called internet.
Once we have done that, your three points are completely irrelevant, because then only those who the government sees as journalists can actually do journalist work. Everybody else trying to do it would be breaking the law.
I mean, what could possibly go wrong?
That’s amazing. It would take an entirely new sub-branch of philosophy to address those ideas…
It would also create a lot of jobs!
