Senator Elizabeth Warren is standing by President Biden, and says he should remain in the race.
Warren says Biden is the Democratic party's nominee and has been an excellent president who works hard for American families.
Warren challenged Biden for the 2020 Democratic nomination for president, but has been a strong supporter of Biden since she dropped from the race.
She now serves on the campaign advisory board for the president.
