A dress rehearsal for next week's presidential inauguration at the U.S. Capitol.
Stand-ins for U.S. President Barack Obama and First Lady Michelle Obama take part in the mock ceremonies.
Obama's swearing-in ceremony on January 21 is expected to draw up to 800,000 people. That's fewer than the close to 2 million who flocked to Washington in 2009.
The official Inauguration Day is January 20th. Because the 20th falls on a Sunday, Obama will take the official oath of office at a private ceremony that day and then attend the public swearing-in ceremony January 21st.
