"Today, on this January day, my whole soul is in this: bringing America together, uniting our people, uniting our nation," Joe Biden said in his inaugural address. He was sworn in as the United States' 46th president on Wednesday, and he pledged to be a president for all Americans -- even those who did not support his campaign. Biden spoke shortly after Kamala Harris made history by becoming the country's first female, first Black and first South Asian vice president. He said this Inauguration Day was a triumph for democracy. "The will of the people has been heard, and the will of the people has been heeded," Biden said. "We've learned again that democracy is precious. Democracy is fragile. And at this hour, my friends, democracy has prevailed." This was the first time in 150 years that the outgoing president has boycotted his successor's inauguration. Donald Trump, still bitter about the election, skipped the ceremony and many of the time-honored traditions that come with the peaceful transfer of power. He departed Washington early in the morning, giving a speech at Joint Base Andrews before flying to Florida.
