I'm not necessarily a Sean Spicer fan myself. But the media demonstrates their embarrassing bias against him on a regular basis.
The media loves to invent FakeNews, and sell their fiction to the gullible. Examples include Gerrald Ford our most athletic President as the Klutz, or Dan Quayle as the idiot because he read a school provided cue card where the school spelled Potato wrong, and they played him as the idiot. Spicer is being repeatedly attacked for saying the same things that Democrats say, but the media gives them a pass on. To me, that reflects on the medias naked hypocrisy and bias, more than on the administration. Where are the Social Justice Warriors when the injustice is against anyone with an (R) after their names?
Sean Spicer (WhiteHouse Press Secretary) while talking about Assad (Syria) use of chemical weapons, misspoke (said something completely true but inartfully worded) and corrected himself (clarified that "as a tool of war" and not talking about gassing civilians) and apologized all in the same news-conference. Far left outfits like CNN, CBS, MSNBC, Snopes, Politifact, all ignored the correction/clarification and used the gaff as a way to attack Spicer and Trump, and spin a non-story into evidence of why they were a bad administration. They also ignored many cases where others on the left had said the same truth. Lies of omission, and sensationalism, are evidence of propaganda/FakeNews.
