Obama to appear on Letterman TV show Monday

LOS ANGELES, Sept 15 (Reuters) - President Barack Obama will appear on comedian David Letterman's late-night talk show next week, the CBS network said on Tuesday.

Obama will be the sole guest on the Monday, Sept. 21, broadcast of the "Late Show with David Letterman", CBS (CBS.N) said.

Obama became the first sitting president to appear on any U.S. late-night talk show when he was a guest in March on NBC's "The Tonight Show," hosted by Jay Leno.

The president's Monday appearance on Letterman's program marks the first time Obama has been on the program since being elected president last November. He has made five previous appearances on "The David Letterman Show", including one in September during his campaign for the White House.
