Some context.
Joy-Ann Reid was responding to a segment just preceding her show. This concerned the simultaneous placement of statues of a nude Donald J. Trump in prominent areas of five major American cities. They depicted him as grossly overweight, with a teeny tiny penis and no balls. Each bore a plaque reading, "The Emperor Has No Balls."
In the related segment, local newscasts showed crowds gathered around the statues, laughing, pointing and taking pictures. Their cameras mostly pointing below the waist. The one in New York's Central Park was removed by the Parks and Recreation Department, with the notification that unauthorized nude statues are not allowed to be "erected, no matter how small." *
Ms. Reid was responding to the light-hearted, rather ribald nature of the story and the humorous responses by the people on the street in the segment, laughingly referring to it as being a "small problem" and the like.
Of course, this all is an outgrowth of the charge by Marco Rubio about Trump's "tiny hands" - and "You know what that means" - which of course prompted Trump in their next televised debate to assure everyone that he had "no problem" in that area. A case of TV-TMI. The inside joke is that the Donald is terribly sensitive about the size of his hands ("Big League" or "Bigly"). In a magazine article years ago, he had been ridiculed for having tiny hands. Trump immediately indignantly responded that he had perfectly normal-sized hands, and for years thereafter the writer received xerox pictures and pencil outlines of his hands to prove the point.
* According to the Washington Post, the artist "Ginger" once considered voting for Trump, but decided against it after the Republican nominee made fun of a reporter who had a disability. He has family members with disabilities.
