No matter how the rest of the night goes, Pete Buttigieg already has made history. The mayor of South Bend, Indiana, is the first openly LGBTQ candidate to stand on the stage and take part in a presidential debate.

Talking about the need for affordable college, Buttigieg also mentioned his husband, Chasten, who is a teacher. It was the first time that a presidential candidate has referenced a same-sex spouse during a debate.

Chasten Buttigieg, tweeted a photo showing him helping Pete Buttigieg with his tie. “You’ve got this,” he said.

Pete Buttigieg was one of 10 candidates taking part in the second day of Democratic debates in Miami.
