An Obama handler reaches out to Rodman's PR guy proposing this trip. Who paid for the trip? Rodman didn't go alone He's walking trouble. Rodman hasn't a clue he's being used. He's the same guy making his 2nd appearance on Trump's 'Apprentice' show after being booted the first time round for drinking.
Un knows his country 75 years behind the rest of the world, unable to continue their nukes when they can't feed their own. Un, (or China) agrees for the "Worm" to do a buckets visit. If nothing comes of this or there's blowback, China, NORK and Obama are MIA bout this.
If 'cultural exchanges' result leading to Obama/Un meeting, Rodman is to Obama what PingPong and Pandas were to Nixon.
