Every American president has taken the same oath of office that President Barack Obama took earlier today - every president except one.
Franklin Pierce, the only president to hail from New Hampshire, took a slightly different oath at his inauguration on March 4th, 1853 (in those days, presidents began their terms in March instead of January).
Dr. Peter Wallner wrote a two volume biography of Franklin Pierce. He told NHPR's Brady Carlson that Pierce began his four years at the White House with several unique inaugural flourishes - at a time of huge personal and political challenges.
