Symone Sanders, who has just joined Joe Biden's presidential campaign as a senior adviser, must have reconsidered her earlier position on Democratic Party leadership.

In November 2016, shortly after President Trump's victory, Sanders told CNN's Brianna Keilar that "we don't need white people leading the Democratic Party right now."

"The Democratic Party is diverse, and it should be reflected as so in our leadership and throughout the staff at the highest levels from the vice chairs to the secretaries all the way down to the people working in the offices at the DNC," she added.

The comments were puzzling at the time, considering Sanders, an African American, had earlier served as press secretary for Vermont Sen. Bernie Sanders' presidential campaign. Since leaving that position, she has worked as a political strategist and CNN contributor.

Biden formally announced his candidacy Thursday morning in a YouTube video that focused on the 2017 response by Trump to white nationalist protesters in Charlottesville, Va.

Most polls of Democratic primary voters give Biden a slim lead over Bernie Sanders in the race for the party's nomination.
