Over a million attend Barack Obama's second inauguration

After having his traditional luncheon at the Congress, Obama and the First Lady drove by the parade route to the hundreds and thousands of cheering crowd who had lined up for hours on Monday, some even waiting since early in the morning. "Obama, Obama" and "Four more years!" chanted the crowd. Many simply screamed and waived the American national flag.

When Obama and Michelle came out of their vehicle and walked for a short distance, both of them waved to the cheering crowd.

The First Lady, who was wearing deep purple gloves, occasionally clapped when the two weren't holding hands.

Many onlookers waved flags and clicked pictures.Crowds waved and cheered from several rooftops along Pennsylvania.

As the first couple walked some in crowd chanted: "Fired up! Ready to go!" - a popular election slogan for the US President.

Vice President, Joe Biden, and his wife, Jill, also took some time to walk part of the parade route, with Biden periodically jogging over to the sidelines to shake hands with people across the barricades.
