“I became aware of the AP bias via its editorializing about 20 years ago”
I cancelled my local paper over 30 years ago when they printed a story from the AP about a crime in which a “military style assault pistol” was used. I later read that the gun was a Colt 1911.
AP publishes a “style book” that has been a standard reference for mainstream media for decades.
In 2013 their “style book” declared that the phrase “illegal alien” should not be used.
Then the mainstream media stopped using it.
