evidence: Vice President Kamala Harris has referred to participants in the Democratic presidential campaign as "joyful warriors," and "joy" has been a theme at the party’s rallies and convention. Instagram posts, however, have falsely claimed the phrase "strength through joy," which echoes a Nazi-era program, has become a Harris campaign slogan. [...] An Aug. 25 Instagram reel begins with a narrator saying, "I’m sure by now you’re heard Kamala Harris running around the country. We’re gonna bring back joy! I want you to Google ‘strength through joy.'" The reel then displays a Wikipedia page and a webpage on German history that describe "Strength Through Joy" as an organization in Nazi Germany that was a division of the national labor organization. [...] We could find no use of the phrase "strength through joy" as a slogan or message in the vice president’s remarks or rallies. The prominent slogan on the Harris campaign homepage is, "Let’s win this." The official campaign merchandise includes a variety of phrases, including, "Yes she can" and "When we fight, we win."
