President Joe Biden said Wednesday in an exclusive interview with ABC "World News Tonight" anchor David Muir that, "yes," he planned to run again in 2024 -- and if his predecessor, Donald Trump, runs, then it would "increase the prospect" even more.

       "Do you plan to run for reelection?" Muir asked Biden during a sit-down interview at the White House.

       "Yes," the president replied. "But look, I'm a great respecter of fate. Fate has intervened in my life many many times. If I'm in the health I'm in now -- from a good health. And, in fact, I would run again."

       Biden, at age 78, became the oldest person sworn in as president when he took office earlier this year, and questions about whether he would seek a second term have followed him throughout his presidency.

       With Biden's popularity sagging, White House press secretary Jen Psaki told reporters last month that Biden did intend to run again.

       Last year before the election, Biden had told Muir he "absolutely" planned on being president for eight years if elected.
