"We're just… not quite there yet, and I may not get there in time to make it feasible to be able to run and succeed because there's certain windows that will close, but if that's it, that's it, but it's not like I can rush it," Biden said in an interview with America Magazine.
Biden explained that whether he would join the race remained a "family decision" and would be determined if such a move would be "good for the family."
Earlier in the summer, Biden’s eldest son Beau died of brain cancer, and the Vice President said his son’s death has affected his decision to run for president.
In August, Biden appointed a former presidential campaign spokesperson, Kate Bedingfield as his Communications Director, a move that caused many to speculate that he would soon announce his candidacy.
Biden unsuccessfully ran for president in 1988 and 2008, and speculation has picked up in recent weeks of a possible third presidential bid.
In August, White House Press Secretary Josh Earnest said that Biden would make a decision on whether or not to run in the 2016 race by the end of summer.
