WASHINGTON - For the second time, President Barack Obama took a public oath of office today.

Obama took the oath in front of an estimated 700,000 spectators on Capitol Hill in Washington. 

The president was joined by his family and used Bibles once used by Abraham Lincoln and Dr. Martin Luther King Jr.

In his relatively brief 18-minute inaugural address, Obama encouraged Americans to come together to face the challenges ahead.

"America’s possibilities are limitless, for we possess all the qualities that this world without boundaries demands: youth and drive, diversity and openness, and endless capacity for risk, and a gift for reinvention," Obama said.

Obama also mentioned pushing for equal rights for the gay community and equal pay for women.

"Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law,” the president said. “For if we are truly created equal, then surely the love we commit to one another must be equal as well."
