[The issue now days is that the 4th estate has taken sides.]
Do you think Trump and his long time feud is in some way (if not mostly) responsible for that?  Of course, we've always had bias in the news and thus why it is always suggested to exercise a bit of skepticism.  Also, it cuts both ways with varying degrees.  I believe it was the recently deceased Ailes that admitted that Fox News would pursue a conservative bias to "correct" a lack of journalistic integrity.  I guess no one ever told him that the way to fix a lack of journalist integrity is not to pander to the other side or pedal "alternative facts" but to increase the frequency and quality of verification.
