"Katy Perry is doing a benefit concert for one of my opponents in Iowa, so in response, I thought I would offer this up for Taylor Swift," O'Malley said.

O' Malley played an acoustic version of Taylor Swift's song "Bad Blood" when he sat down with the ladies of  "The View" on Tuesday's taping.

The song is rumored to be about a feud between Swift and Katy Perry.

Perry is planning a benefit concert for Hillary Clinton on Saturday.
