By Thursday, at least three instances of the prime minister caricaturing people of color had surfaced, throwing his re-election campaign into turmoil before the election next month.

Details: On Wednesday, Time magazine published an image showing Mr. Trudeau dressed in brownface for an “Arabian Nights”-themed gala in 2001 at a school where he was a teacher. While apologizing for that image, Mr. Trudeau also admitted to dressing up in blackface while performing a Jamaican folk song in high school.

On Thursday, a Canada-based news organization posted a video showing the prime minister in the early 1990s dressed in blackface and an Afro wig.
