President Obama and Vice President Biden Take the Oath of Office

Today, in two separate, private ceremonies, President Obama and Vice President Biden were officially sworn into office, marking the start of the second term. (The Constitution mandates that the President takes the oath on January 20. Since that date falls on a Sunday this year, the public inauguration ceremony and festivities will take place tomorrow, January 21)
