What on Earth did Hillary spit into that glass after her coughing fit in Cleveland?

Hillary Clinton’s Labor Day appearances, during which she twice dissolved into coughing fits, is yielding some bizarre mysteries.  Startling, in fact.

I apologize to readers in advance for what follows in mystery #1.  If you have just eaten or have a sensitive equilibrium when it comes to digesting food, perhaps you’ll wish to skip the video embedded below.  It shows that when Hillary Clinton was offered a drink of water to stem her coughing, she spit something into the glass.  It appears to be green and vaguely spheroid.

No wonder Washington Post political writer Chris Cilizza demands, “Can we just stop talking about Hillary Clinton’s health now?

Wouldn’t want to raise any awkward questions, after all.
