Hawaii radio announcer campusattheaggiedotorg is the email address the student newspaper uses for campus news tips. You know more about the background and the announcer than any of us, so it might be better for you to send the email. I don't think my friend at the Aggie still works there, so I can't be much further help.
I see the paper going two ways with this. They might want to call him out and get engaged, or alternately might feel that if nobody from Davis heard the comments in the first place then it doesn't affect them and won't be appreciated by the cheerleaders to dwell on it. Can't hurt to at least notify them though.
