Disoriented Trump wanders off G-20 stage saying "Get me out of here" on hot mic

On stage at the G-20 summit on Saturday, Trump suddenly wanders off, for no apparent reason, leaving the president of Argentina standing alone. A staffer runs after him, trying to corral him back. We then hear Trump on a hot mic saying, 'Get me out of here.' The Guardian captured it on video, which @TopRopeTravis tweeted here:

Oh my lord.
Trump just wandered right off the stage, leaving the Argentinian president all by himself.
A staffer is then observed attempting to stop and retrieve Trump.
Ladies and gentlemen... Donald Trump.

But this is nothing new. Watch how Trump zombie-steps away from Prime Minister Netanyahu last year in Israel. Yikes.
