The warning was issued to CBS Evening News anchor Tony Dokoupil in Michigan after Trump finished taping a 13-minute interview.
Leavitt stated that Trump would “sue your ass off” if the interview was not aired in full, though some CBS employees initially thought she was joking.
CBS News confirmed it had already planned to air the interview unedited and in its entirety, a decision made independently.
This incident follows a previous lawsuit by Trump against CBS over the editing of a '60 Minutes' interview, which resulted in a $16 million settlement.
