Where
Washington, D.C.
Part of
Zachary Taylor becomes 12th president; the Atchison 'president for a day' legend

Associates claimed Atchison was acting president for 24 hours because neither Taylor nor Fillmore had been sworn in on March 4.

Under the Presidential Succession Act of 1792, the Senate president pro tempore followed the vice president in the line of succession. Since Vice President-elect Millard Fillmore and Taylor had not been sworn in on March 4, Atchison's friends claimed he was acting president from March 4 to 5.
