I expect some agenda from mainstream media, whether liberal or conservative, but propaganda like this from "NowThis" is quite dishonest.
But Facebook is not news media, I think it's imperative for them to be neutral, plus they promised they wouldn't censor conservative posts.
"NowThis" was founded by Huffington Post founder and former chairman Kenneth Lerer and former Huffington Post CEO Eric Hippeau. It's as liberal as it gets.
Now the video in question is about Trump's immigration policy in reference to what happened in Orlando. I honestly think it's quite understandable. I mean his reasoning about it.
