The AP is still mostly in the political center and sometimes "skews left" a bit according to the media bias chart everyone I know references:

(I expect a lot fewer people to reference that chart in the future unless they fix the new user interface)

These measurements do feel a bit arbitrary, since our definitions of left and right bias are subject to change. For example, one interesting thing about the AP is that their stylebook used to urge their reporters to avoid even using the word "Palestine," one of many ways they put their thumb on the scale in favor of Israel in that conflict. (not sure what it says today) They somewhat famously fired a reporter for having participated in some college activism related to the Arab-Israeli conflict that would seem very quaint and anodyne today, a firing that stirred up journalists and was pretty widely regarded outside the right wing media sphere as unfair. (ironically, a week or two later the IDF destroyed the AP's Gaza office in an airstrike)
