In an emotional interview with talk show host Stephen Colbert, US Vice-President Joe Biden has said he has still not decided whether he will run for president.
“I’d be lying if I said that I knew I was there,” Biden said on Thursday.
Supporters have encouraged Biden to run as fellow Democrat Hillary Clinton’s poll numbers have declined.
However, he has questioned whether he has “emotional energy” to run after the death of his son Beau in May, reports the BBC.
“Nobody has a right, in my view, to seek that office unless they’re willing to give it 110% of who they are. And I am, as I said, I’m optimistic, I’m positive about where we’re going,” Biden told Colbert. “But I find myself – you understand it – sometimes it just overwhelms you.”
Biden, 72, failed in his bids for the White House in 1988 and 2008 before becoming Barack Obama’s running mate.
Representatives for Biden said the vice-president would make a final decision by October.
Some had speculated that Biden would use the high-profile appearance on Colbert’s new show as a way to launch his campaign.
Instead, the interview with Colbert focused on his son Beau and how Biden is coping with the loss.
Choking up at times, Biden talked about his son and his last days.
“‘Dad, I know how much you love me. Promise me you’re going to be all right’,” Biden recalled his son telling him.
