evidence: Minnesota Gov. Tim Walz (D) and Ohio Sen. JD Vance (R) met on the debate stage Tuesday night in what is likely to be the only vice-presidential debate of the 2024 election cycle. Throughout the event, the two candidates sought to depict their opponents’ stances as at odds with their running mates, while sparring with civility over immigration, abortion, the economy, and more. [...] When pressed by moderators to explain his claim that he was in Hong Kong during the Tiananmen Square protests, Walz said he "misspoke" when he said he had visited Hong Kong on June 4, 1989, the day of the Tiananmen Square massacre. On Tuesday, CNN reported that Walz claimed in a June 2019 radio interview to have been in the city when the massacre unfolded. CNN also cited Walz saying during a 2014 House hearing that he "was in Hong Kong in May 1989" and that, "as the events were unfolding, several of us went in. And I still remember the train station in Hong Kong."
