Mayor of Chicago Rahm Emanuel will make his first visit to the LATE SHOW with DAVID LETTERMAN, Monday, Sept. 9 (11:35 PM-12:37 AM, ET/PT) on the CBS Television Network.
Also noted in the press release, perhaps out of concern for Emanuel's notoriously salty language: "RATING: TV-PG (Rating may change on day of broadcast due to specific subject matter.)"
