Yes, Zeke Miller of Time sent out a tweet about it. Apparently it was on a table behind a camera man. Of course, it was to get things stirred up - Trump hates MLK (his niece, Alveda, has been pro-Trump and was at the prayer service at the Cathedral and the entire family went over and greeted her.
Ah, so it was a Time reporter that sent the tweet? I thought Time had reported it online/in the printed copy. That’ll teach me to quit skimming articles!
