Between 2016 and 2019, media outlets often mentioned Biden as a likely candidate for president in 2020. When asked if he would run, he gave varied and ambivalent answers, saying "never say never". At one point he suggested he did not see a scenario where he would run again, but a few days later, he said, "I'll run if I can walk." A political action committee known as Time for Biden was formed in January 2018, seeking Biden's entry into the race. He finally launched his campaign on April 25, 2019, saying he was prompted to run, among other reasons, by his "sense of duty."
