'It's about time:' Biden delivers speech alongside two women

The seating arrangement carried a symbolic meaning for the advancement of U.S. women in recent decades, since Harris and Pelosi stand first and second in the presidential line of succession, respectively.

Harris, the first woman and the first Black and Asian person to serve as vice president, sat to Biden's right. Pelosi, who became the first woman speaker of the House of Representatives in 2007, sat to his left.

"Madam Speaker, Madam Vice President," Biden said as he addressed the crowd. "No president has ever said those words from this podium, no president has ever said those words. And it's about time!"
