After taking the oath of office, Joe Biden said that the Inauguration Day was a celebration of democracy and that the "the will of the people has been heard."
"Today we celebrate the triumph, not of a candidate, but of a cause — the cause of democracy. The will of the people has been heard, and the will of the people has been heeded. We've learned again that democracy is precious. Democracy is fragile. And at this hour, my friends, democracy has prevailed.
Earlier in his speech, he said: "This is democracy's day, a day of history and hope, of renewal and resolve," Biden said.
"America has been tested anew, and America has risen to the challenge," he added.
He said the "cause of democracy" is celebrated today.
"The will of the people has been heard and the will of the people has been heeded," Biden said.
