David Letterman is on a roll this week, scoring not one but two presidential interviews.

Tonight, President Barack Obama will appear on "The Late Show with David Letterman," presumably to discuss health care, but perhaps also to discuss the various jackass qualities of Kanye West also, according to a WarmTV source inside the taping, about former President Jimmy Carter's recent comments on race, and about his family's adjustment to the White House.

Tomorrow night, Letterman will have former President Bill Clinton on the show.

"Late Show" airs at 11:30 on CBS.

This probably won't stay online long before the copyright mavens strike it down, so check it out pronto if you care -- night two of U2's weeklong performance stint on CBS' "Late Night With David Letterman." If you like what you hear, the band will be playing on Letterman again tonight.

(Thanks, Doug.)
