President Bush's inauguration will mark the 55th time in more than 200 years that a U.S. president has taken the constitutionally mandated oath of office.

The theme for Mr. Bush's second inauguration is "Celebrating Freedom, Honoring Service." Officials say that with the nation at war, they want to pay special tribute to U.S. military forces and their families.

More than 200-thousand people are expected to observe the swearing-in ceremony on the steps of the U.S. capitol.

Following the 35-word oath administered by Supreme Court Justice William Rehnquist (at noon on Thursday, January 20th), the president will outline his priorities for the next four years in his inaugural address.

Afterwards, the president and first lady Laura Bush will lead a parade up Pennsylvania Avenue to the White House.

Nine special parties will be held the evening of the inauguration, including an invitation-only Commander-in-Chief ball for members of the military who have served in Iraq and Afghanistan.
