It's Biden's speech, but Kamala Harris and Nancy Pelosi also made history

In an era of political "firsts," Wednesday evening offered one of the most symbolic when, for the first time, two women flanked an American president on the dais of the House Chamber as he delivered an address to a joint session of Congress.

President Biden's remarks focused on his first 100 days in office, the sweeping infrastructure proposals he's unveiled and the January 6 attacks at the U.S. Capitol. But it's the moment that formally launches the proceedings that may be most enduring. According to protocol, Vice President Kamala Harris called the proceedings to order and House Speaker Nancy Pelosi formally introduced Mr. Biden to Congress as president for the first time. It's a moment that lasts a few seconds and usually isn't seen by the global television audience. But it was the pinnacle of a remarkable rise for two political figures from California's Bay Area.
