evidence: FORMER PRESIDENT DONALD TRUMP: The people on television say my dog was taken and used for food. So maybe he said that and maybe that's a good thing to say for a city manager. [...] FORMER PRESIDENT DONALD TRUMP: I said that sarcastically. You know that. It was said, oh we lost by a whisker. That was said sarcastically. Look, there's so much proof. All you have to do is look at it. And they should have sent it back to the legislatures for approval. I got almost 75 million votes. The most votes any sitting president has ever gotten. I was told if I got 63, which was what I got in 2016, you can't be beaten. The election, people should never be thinking about an election as fraudulent. We need two things. We need walls. We need -- and we have to have it. We have to have borders. And we have to have good elections. [...] LINSEY DAVIS: President Trump thank you. And that is our ABC News presidential debate from here in Philadelphia at the National Constitution Center. I'm Linsey Davis.
