Modern pop music isn't quite up my ally, so I wasn't watching last night's Grammys. One of the "highlights" of the evening per the BBC was Busta Rhymes' takedown of the new president, christening him "Agent Orange." That's an unveiled dig at his skin-tone and his toxicity.
However, the metaphor might be far more apt than Busta implied. If taken in the context of "drain the swamp", Agent Orange is an effective defoliant. It doesn't drain the wetlands, but it does make the swamp critters easier to see and thus to catch; in a more sinister vein, it can also take out the other side's crops and starve them out.
However, it was show to be a strong carcenogen, hurting both the Vietnamese and US soldiers appling it during the Vietnam War.
Both seem to be apt; sending Trump in to reform Obama-era excesses has some rather toxic side effects.
