If the President of the United States is a liar, it is the duty of responsible media to point it out. How are we going make decisions about him if we are not aware of his failings. Likewise, if he and his associates are in a position to enrich themselves by being in office, I want to know about it. If reporting facts casts a bad light on his administration, that's his tough luck.
Balanced media is not reporting 1 good decision and 1 bad decision. If Trump tells 5 lies for every truth, than it should be reported proportionately. That's not bias, that's statistics.
