Over a million attend Barack Obama's second inauguration

In 2009, when Obama swept a war-weary America with a promise of change and scripted history by becoming the first African American President, a record 1.8 million people had flooded the National Mall to witness his swearing in.

This year, the inauguration officers of the presidential inauguration committee and security officers associated with the planning had expected around 800,000 people to turn up for the event.

However, officials associated with the crowd management said they estimated that at least a million people had attended the inauguration event in the US Capitol yesterday, surpassing expectations.

According to Washington Metro Transit Authority - which runs the city's metro system - by 4 pm more than 538,000 people had used the metro system and they were expecting the number to cross much more by the end of the day.

The huge crowd that crossed a million mark took many organisers by surprise, and is indicative that Obama still enjoys much of the popularity he held at the beginning of his first term.

Obama himself wanted to have a last glimpse of this cheering crowd overlooking the National Mall from the Capitol Hill. "I want to take a look one more time. I'm not going to see this again," he said as he was walking away from the Capitol Hill after delivering his speech to the hundreds and thousands of people.

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.
