Donald Trump’s first major interruption of Hillary Clinton at Monday’s presidential debate came when she made a claim about his past remarks: “Donald thinks that climate change is a hoax perpetrated by the Chinese,” she said. “I think it’s real.”

Trump responded, “I did not. I do not say that.”

He did. Here is the tweet proving it:
