It is possible that the #MAGAbomber believed that "The Fake News is The Enemy of The People" as Donald Trump has Stated.

 Then the #MAGAbomber took action to destroy That Target... CNN... I wonder if Fox News is also the enemy of the people... Why not MSNBC? They televise anti-trump shows... Sometimes they seem like an Orwellian Group Hate. Does MSNBC feel slighted? Like a sister who wasn't invited to the Prom?

#MAGAbomber is a Trump Supporter who had Pro-Republican Stickers all over his Van. Anti-Democrat pictures with Target images photoshopped on them... as if he was pointing a gun with a rifle sight at Donor George Soros and Filmmaker Michael Moore.

So if fake news media = enemy of the people, which outlets fall into that category?

Quite a few. The first time that Trump used the phrase, “enemy of the American people,” he identified the New York Times, NBC News, ABC, CBS, and CNN. He’s also called the Washington Post “fake news” several times. 

Not mentioned is Fox News or Rush Limbaugh... Bright Bart or The Heritage Foundation and The CATO Institute.
