Vermont Sen. Bernie Sanders says he is open to another run for the presidency in 2024, if Democrat President Biden decides not to seek a second term.

Sanders is an Independent but ran for President in 2016 and 2020 as a Democrat.

“In the event of an open 2024 Democratic presidential primary, Sen. Sanders has not ruled out another run for president, so we advise that you answer any questions about 2024 with that in mind,” reads a memo from a top Sanders political adviser.
