I am literally unaware of a single mainstream television station, newspaper, or magazine that hasn't been caught in blatant politically-motivated lying.
My rule-of-thumb for news sources is: I need to see zero lies for at least two years before I trust them again. This is different than mistakes which are immediately and prominently corrected with front-page stories as big and bold as the original mistaken story. I'm unaware of any currently mainstream TV/newspaper/magazine that ever retracts their "mistakes" anywhere close to this standard as well. Hence, the lack of trust.
