A painter on Tuesday covered up messages people wrote in chalk on the barriers the US Secret Service placed around a small park adjacent to JD Vance’s house in Alexandria. Cops looked on while the painter worked. The park, which features a tot playground and a labyrinth, has become an unlikely nexus of national and local news in recent weeks. The feds closed it off in late August, then announced it would be open on some days. It’s closed Tuesday. Over the weekend, someone left a box of chalk atop the barriers, and passersby applied messages like “Harris 24,” “Not Going Back,” and “Love Everyone.”
