I didn't find the media coverage -- whether print or broadcast -- to be reporting that Mueller was going to nail Trump, it was just a matter of time. I wonder sometimes if people making those claims actually read or watch the news. I generally find reporting -- I'm not talking about op-eds (which are not reporting) -- to be pretty neutral.
This is from an NPR report of almost one year ago
I don't find anything breathless or even unusual about this report, it seems like straight-up news reporting of the kind that most news media organizations routinely produce. Not to say there wasn't a lot of bad news involving Trump. There definitely was. But it was news.
