South Bend Mayor Pete Buttigieg is defending his appearance on a Fox News Sunday night saying, “Fox News Town Hall tonight shows that we can connect with people anywhere while standing firm on our values.” The Democratic presidential candidate used the appearance to lay out his platform to an audience that may not know much about him. He also wasn’t shy about criticizing two of the network’s stars, Tucker Carlson and Laura Ingraham.

Many of those who watched the town hall, are giving Buttigieg high marks.

It looks like Buttigieg did have at least one critic watching though. By our count, we believe this is the first time Donald Trump has mentioned the Mayor on Twitter.

Brit Hume, one of Fox News’ most well-known analysts took exception with Trump’s tweet writing back, “Say this for Buttigieg. He’s willing to be questioned by Chris Wallace, something you’ve barely done since you’ve been president. Oh, and covering candidates of both parties is part of the job of a news channel.”
