Biden says it "remains to be seen" if he will run for president again in 2024.
He said he had expressed his intention to run again, but "it's just an intention."
Pelley asked Biden if he was committed to a 2024 run, or if "certain conditions" would factor into that decision.
But it's just an intention," Biden said.
If Biden — who is approaching 80 — were to run and win, he would become the US' oldest sitting president, breaking his own record.
