Obama World Tour 2009: Next Stop, Dave

President Obama's health care world tour will make a stop on "Late Show with David Letterman" Monday.

Here's the release just issued by CBS:

President Barack Obama will visit the LATE SHOW with DAVID LETTERMAN, Monday, Sept. 21 (11:35 PM-12:37 AM, ET/PT) on the CBS Television Network. He will be the sole guest on the broadcast.

President Obama's appearance will mark the first by a sitting U.S. President on the LATE SHOW and his first visit back to the show since his election. In total, this will be President Obama's sixth visit to the broadcast – he last appeared on the LATE SHOW Sept. 10, 2008 during the height of his 2008 Presidential election campaign.

Obama's last late night visit, of course, was on "The Tonight Show with Jay Leno," earlier this year.
