Trump went off on what one guest called a "bizarre tangent." He described being home alone in the White House over Christmas "while the Democrats were in Hawaii."
Trump described opening his curtain to look at Secret Service agents swarming the White House lawn. "They're in the trees, on the lawn," he said.
He said he saw agents wearing night vision goggles. "They're in blackface," Trump added, jokingly referring to the masks over the agents' faces.
Trump joked that the agents were "in blackface" because of the masks so maybe "they have to take them away," according to two sources who were there. (The sources assumed Trump was referring to the recent controversy in which the Democratic Virginia Gov. Ralph Northam was caught in a racist costume in his 1984 medical school yearbook.)
