All media outlets seem to co-operate against Trump with coordinated headlines. There are many examples, notably:

AJ+ is constantly running pro-Hillary and anti-Trump videos which get massively promoted by Facebook's algorithms. Just ready any news item on Hillary/Trump on any respectable media outlet and you will 9/10 times read a negative undertone for Trump and a positive one for Hillary.
It's overly biased and nobody seems to really bother. Again, this is not about being in favor of Trump or Hillary, just how the media has clearly already picked sides and is obviously creating a positive imago for one candidate to the public opinion which is often based on mainstream media.
