ABC News sent advisories to the 10 Democratic presidential candidates participating in Thursday night's debate asking they not swear during the event in Houston.



“We wanted to take this opportunity to remind you that, as the debate will air on the ABC broadcast network, we are governed by Federal Communications Commission indecency rules,” ABC News political director Rick Klein wrote in a memo forwarded to the campaigns that was obtained by The New York Times.



“Candidates should therefore avoid cursing or expletives in accordance with federal law,” Klein added.

The Hill has reached out to ABC News for comment.
