Spiteful interloper who carefully chooses his words, relishing his part in the political upheaval of a nation-state which has effectively imprisoned him in a London embassy? Maybe.
How's that working out for him? Trump is no more in his court than Clinton was, Ecuador has cut off his Internet access, and he's squandered any support he had by helping elect an even bigger idiot.
The source of that purported joke is "sources in the State Department" that talked to TruePundit. If you believe TruePundit had sources in Clinton's State Department, you might believe that Seth Rich leaked the DNC emails to WikiLeaks after participating in child sex trafficking in the basement of a basement-less pizza parlor.
Yeah I dunno. TYT[1] (not a Trump mouthpiece) seem to agree her non denial as likely admission that it was said. "[Clinton] probably said it as a [frustrated] joke".
