While Inauguration Day is underway this holiday of Martin Luther King, Jr. Day, and hundreds of thousands of people are gathered outside the United States Capitol building in Washington, D.C., to watch President Barack Obama, 51, get sworn in for his second presidential term, the critics who count — Obama's family, wife Michelle Obama, 49, and daughters Malia, 14, and Sasha, 11, have already given their verdict.

Many who are watching today do not know that Obama was actually officially sworn in on Sunday in a private ceremony in the White House Blue Room, where he began his second term after swearing on Michelle's powder blue family Bible.

After the official swearing in, the children expressed their support for their day. "I'm so happy," said Malia, reports People. "Yay!" she added, while the younger Sasha said, "Good job, Dad."

"I did it," Obama replied, and Sasha gave him the most resounding endorsement of the day. "You didn't mess up," she said.

Singers Kelly Clarkson and Beyonce will perform at the public Inauguration Ceremony this afternoon. Former Presidents of the United States Bill Clinton and Jimmy Carter will be present.
