President Barack Obama has begun his second term by declaring that the nation's "possibilities are limitless."
Speaking before a flag-waving crowd of hundreds of thousands on the National Mall, Obama said a decade of war is ending, and the nation's economy is recovering.
Moments after taking the oath of office on a crisp day in the nation's capital, Obama said, "We are made for this moment, and we will seize it, so long as we seize it together."
In his second inaugural address, Obama didn't dwell on any first-term accomplishments, but instead looked to hard work ahead in a country still grappling with a sluggish economy. And he urged Washington to find common ground over his next four years.
He rejected the idea that the nation "must choose between caring for the generation that built this country and investing in the generation that will build its future."
He also said the nation must "respond to the threat of climate change" and tackle the issue of immigration reform. And he said it must protect its children from the kind of violence that erupted in a Newtown, Conn., elementary school.
Obama earlier placed his hand on two Bibles -- one that was used by Martin Luther King and the other used by Abraham Lincoln -- and recited the oath of office.
Vice President Joe Biden was also sworn in for his second term. President Barack Obama has signed documents officially submitting top administration nominations to the Senate.
In a traditional inauguration signing ceremony in the U.S. Capitol after he took the oath of office, Obama affirmed the nominations of John Brennan to be director of the CIA, former Sen. Chuck Hagel for secretary of defense, Sen. John Kerry to be secretary of state and Jack Lew for Treasury secretary.
Obama also signed a proclamation to commemorate the inauguration. The proclamation is entitled "National Day of Hope and Resolve, 2013."
President Ronald Reagan established the tradition of visiting the Capitol's President's Room after taking the oath to sign documents and pose for photographs.
Congresswoman Suzanne Bonamici (D-OR) today released the following statement following the second inauguration of President Barack Obama.
"President Obama today laid out a unifying message and a clear direction for his second term. From strengthening our economy and passing a budget that responsibly reduces our deficit, to reforming our immigration system, taking action to address climate change, and preventing gun violence, our country has some difficult decisions to make.
"One thing is clear: it's time to get to work. For far too long, Congress has been mired in gridlock and partisanship with no clear agenda. Today the President set a course for the next four years. While there will be debate and differences, I believe that we can come together to find common ground. I look forward to working with the President and my colleagues on both sides of the aisle to achieve compromise and get things done. It's time to put progress before partisanship."
