It is legit, go check his timeline if you doubt it.
I had good seats during TRUMPS CPAC speech, with a clear view of Gorka who was to the Right of the stage. I can confirm that he was in direct eyesight of myself during the speech in at which time Q posted. Gorka was not on his phone posting at the time, he was locked into the speech. Gorka might be in the loop, may have even posted as Q in the past, but it was definitely not him at that time.
