The near collision went down Friday morning in Reagan National Airport ... according to Politico Playbook, which first posted this amazing pic. DTJ on his phone, anxiously standing at the gate, waiting to begin boarding -- while Mueller's sitting in the gate area reading a newspaper. Perhaps reading a review of his work?
We don't know that they got on the same flight -- they were in a waiting area to catch shuttle buses to other gates -- but that would've been awesome.
