GETTYSBURG, Pa. (AP) - Politicians, historians and others have gathered to honor the cemetery dedication delivered in a matter of minutes 150 years ago by President Abraham Lincoln on the central Pennsylvania battlefield where thousands were killed or wounded during the American Civil War.
Supreme Court Justice Antonin Scalia was also among those assembled Tuesday at Soldiers' National Cemetery to recall the inspirational and famously short Gettysburg Address.
Echoing Lincoln, keynote speaker and Civil War historian James McPherson says the president took the dais in November 1863 at a time when it looked like the nation "might indeed perish from the earth."
Pennsylvania Gov. Tom Corbett says the oration sought to heal the nation's wounds by defining what a nation should be.
Sixteen immigrants are also new citizens after Scalia administered the oath of allegiance.
