WXYZ-TV's Peggy Agar shouted a question to the Democratic presidential candidate during Obama's appearance Wednesday at a Chrysler LLC plant in Sterling Heights.
Agar asks Obama what he's "going to do to help American autoworkers."
He replies, "Hold on one second, sweetie, we'll do a press avail, thanks" but didn't get back to Agar.
On the air later, the station played a voice message Obama left for Agar. Obama apologizes for not getting back to her. He also tells Agar he has a bad habit of calling people "sweetie."
Obama then says: "I mean no disrespect, so I am duly chastened on that front."
