Minnesota Gov. Tim Walz (D), the Democratic nominee for vice president, defended his past misstatements about his military service and his travel to China, arguing there was a difference between mixing up dates and being a "pathological liar like Donald Trump." Walz was pressed during an interview with "60 Minutes" that aired Monday about his past statements in which he said he was present during the Tiananmen Square protests in 1989. "I think folks know who I am," Walz said. "And I think they know the difference between someone expressing emotion, telling a story, getting a date wrong by--you--rather than a pathological liar like Donald Trump." "But I think it comes down to the question of whether—whether you can be trusted to tell the truth," correspondent Bill Whitaker responded. "Yeah. Well-- I can-- I think I can," Walz said. "I will own up to being a knucklehead at times, but the folks closest to me know that I keep my word." Walz's depiction of his travel to China has not been the only incident to come under scrutiny since he joined the Democratic ticket. Republicans have attacked him over his representation of his time in the Army National Guard, specifically that he previously said he carried weapons of war "in war," despite not being deployed into combat.
