She put her own spin on the song by adding a line from "Let's Get Loud."

The inauguration of Joe Biden as the 46th president of the United States and Kamala Harris as the nation's first female vice president on Wednesday was filled with emotional moments. First, Lady Gaga made a triumphant entrance in a voluminous red skirt and black jacket with a symbolic golden bird brooch, to sing the national anthem at the Capitol.

"I pray tomorrow will be a day of peace for all Americans," she wrote on Instagram hours before the inauguration. "A day for love, not hatred. A day for acceptance not fear. A day for dreaming of our future joy as a country. A dream that is non-violent, a dream that provides safety for our souls."

Jennifer Lopez also had all eyes on her as she performed "This Land Is Your Land" a cappella. Although her fiancé, Alex Rodríguez, revealed on The Tonight Show Starring Jimmy Fallon that J.Lo was more nervous about her inauguration performance than she was for the Super Bowl, she was flawless. The singer and actress, of Puerto Rican descent, said a few words in Spanish: "Una nación bajo Dios, indivisible, con libertad y justicia para todos." The new president, whose campaign J.Lo supported, greeted Lopez as she was leaving, visibly moved.

Lopez also shared images from the Capitol prior to the big day, including a video of herself taking a selfie with fans from the military. "What an honor to spend a few moments with these brave men and women," she wrote. "Thank you for your service and sacrifice. I honor you today and everyday. Tomorrow I sing for you and all Americans."

Justice Sonia Sotomayor, the first Latina to serve on the Supreme Court, swore in Kamala Harris as vice president. Harris makes history as the first woman in this role, as well as the first person of Black and Asian descent.

Another emotional moment came when Harris bid goodbye to former Vice President Mike Pence and his wife, Karen Pence, on the steps of the Capitol. Unlike Donald Trump and Melania Trump — who as promised did not attend the inauguration and left Wednesday morning for their home in Mar-a-Lago — Pence was part of the traditional transition of power, joining former Presidents Barack Obama, George W. Bush and Bill Clinton.

After Biden was sworn in, he addressed the nation, promising to be "a president for all Americans." "This is our historic moment of crisis and challenge," he said. "And unity is the path forward. And we must meet this moment as the United States of America. If we do that, I guarantee you we will not fail."
