WASHINGTON -- Four days of parties and pomp are under way in Washington, culminating Tuesday with the swearing-in of the nation's first African-American president.
President-elect Barack Obama arrived at the city's Union Station Saturday evening on board a special train from Philadelphia, recreating the rail trip taken in 1861 by his Illinois predecessor Abraham Lincoln.
Obama used the journey for a rolling history lesson. In Philadelphia, he noted the risks taken by the founding fathers in declaring independence from Britain.
In Wilmington, Delaware, joined by Vice President-elect Joe Biden, he saluted the first state to ratify the U.S. Constitution.
And in Baltimore, Obama hailed the troops at Fort McHenry who beat back the British navy and inspired the poem that became "The Star-Spangled Banner."
The Washington celebrations are being shadowed at every point by heavy security. The FBI has been planning for the inauguration for months. The special agent in charge of counterterrorism says there's no credible intelligence warning of any attack, but he says if anything happens, they're "very, very confident" they'll know how to respond.
