Vice President Joe Biden is not ruling out running for office again, he said Sunday.
Biden, in an interview with ABC News’ George Stephanopoulos on This Week, said he will remain committed to fighting for issues he still cares “deeply” about, including curing cancer, advancing foreign policy, combating domestic violence and reforming the tax system.
“I don’t plan on saying goodbye,” Biden said. “I always judge people who spend a lot of time in public office, say they care about things, and if the day after they leave they no longer talk about them, then I don’t think they cared much about them.”
