It's nice to read a fact check that isn't "everything he said is not even wrong, it's just verbal diarrhea". I'll take someone this wrong over pet-eating bullshit any day:
He has said in interviews and during other speaking engagements that he was in China during the massacre. He was not. He traveled there later that year.
He used to claim he’d been there “about 30” or “dozens” of times, but after APM Reports and MPR News questioned how that was possible, his campaign acknowledged the real number of trips from the U.S. to China was “closer to 15.”
