Rahm Emanuel to appear on 'Late Show,' PG rating subject to change

From the good people at CBS:

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.)"
