evidence: The latest example centers on Walz’s past claim that he was in Hong Kong during China’s deadly Tiananmen Square protests in 1989. Walz moved to China that year to teach English, and he later launched a company that brought U.S. students to the country on educational trips. Several news outlets reported this week that Walz was actually in Nebraska at the time of Tiananmen Square and didn’t leave for China until more than two months after the massacre there. Walz was questioned about the discrepancy during his debate against Ohio U.S. Sen. JD Vance on Tuesday. [...] Walz elaborated further in a brief exchange with reporters in Pennsylvania on Wednesday, saying, "Look, I have my dates wrong." He said he was in Hong Kong in August 1989, not in the spring, and that being there at that time "was profound for me — that was the summer of democracy."
