Inserting Trump in an article generates outrage...outrage is good for publications. I've noticed a lot of publications doing this, as in inserting politics into articles where it doesn't matter. I don't know who to blame; Trump the attention-seeking clown or the media orgs that give him the constant attention, whether positive or negative.
Specific to this article they're saying "the Republican special prosecutor has good reasons to do this (that aren't political)" to cut that argument off.
That's increasingly happening with YouTube videos for pop science and listicles. The creators just have to find some way to twist in some politics, usually with a snide or smug delivery, even if they don't have even a tangential relationship to the video's advertised subject matter. Usually, it's not about Trump but about various political and ideological causes currently popular with twentysomethings. Often it feels like the video was finished and someone went "Oh crap, we forgot to stick in some politics" and went back to add it in.
