Celebrities, politicians and even the President of the United States are taking part in a national effort to encourage people to learn the Gettysburg Address. But the project is also drawing criticism.

Filmmaker Ken Burns, who helped launch the “Learn the Address” project, says President Obama was asked to read the first known version of the Address.

It does not include the words “Under God.” And that has some people upset.

There are five versions of the speech.

A later version was read by an Abraham Lincoln re-enactor at the 150th Anniversary ceremony in Gettysburg.
