The mainstream media seems to have little difficulty in finding things to report on that are not favorable for Trump, whether they were included in a press briefing or not. Trump shouldn't exclude them, but that's a different point entirely. With Obama, everything that went wrong was almost always someone else's fault -
whether it was government shut-downs,
minuscule growth in the economy,
poor roll-out of Obamacare (though he did end up
apologizing for the inconvenience - to his credit), fast and furious,
spying on journalists,
the secret Iran deal,
race relations being worse than they have been in a decade, the VA issues, Benghazi,
being labeled as one of the least transparent white houses in modern history, the IRS targeting conservative organizations, or
releasing terrorists from Guantanamo that returned to the war-front - everything was either someone else's fault, whether it was someone on his staff, a former president, or deemed to be not a big deal. The mainstream media has had a hand in downplaying all of the above. If everything I mentioned above had you rolling your eyes or shaking your head, that's proof that the media shielded Obama from a lot of negative press, and they've successfully gotten you to believe it had nothing to do with Obama or gotten you to believe that it wasn't a big deal. Obama and the media even made the ridiculous claim that his administration was
scandal-free. (You may conversely believe that my media sources have gotten me to believe everything that happened during Obama's presidency was his fault and IS a big deal. To be fair, there may be some truth to that belief, as well.)
