Maddow, O'Reilly join Obama, Bush to recite Gettysburg Address

A production by the Learn the Address project, a program created by documentarian Ken Burns to encourage Americans to learn the Gettysburg Address, brings together several unlikely politicians and media types to recite Abraham Lincoln's most famous speech.

Among those featured in the video are President Obama, former president Bush (43), Fox News anchor Bill O'Reilly and MSNBC's Rachel Maddow. Others: singer Taylor Swift, late night comedian Conan O'Brien and Sen. Marco Rubio (R-Fla.).

This year marks the 150th anniversary of the speech.
