Buttigieg, who is openly gay, said over the weekend that he wishes "the Mike Pences of the world would understand that if you’ve got a problem with who I am, your problem is not with me. Your quarrel, sir, is with my creator."

Pence noted that Buttigieg is trying to stand out from a crowded Democratic primary field.

“But I get it. You know, it’s look, again, 19 people running for president on that side in a party that’s sliding off to the left. And they’re all competing with one another for how much more liberal they can be,” Pence said, according to CNBC.

Pence opposed legislation supporting gay marriage during his time as governor of Indiana and has received frequent criticism from the LGBTQ community for his views.

Pence noted that he “worked very closely with Mayor Pete” and that the two “had a great working relationship” while they were both working in the Hoosier State.

In a post on Twitter on Tuesday, Buttigieg seemingly referenced his previous interactions with Pence.
