US Vice President Joe Biden's associates have resumed discussions about a 2016 presidential run after putting aside such deliberations during his son's illness and death earlier this year.
But Biden has yet to tell his staff whether he will run or personally ask them to do any planning for a potential campaign.
That's according to people close to Biden who spoke to The Associated Press on the condition of anonymity.
The renewed focus on Biden comes amid some signs of weakness for frontrunner Hillary Rodham Clinton, including declines in her popularity in recent polls.
Senator Bernie Sanders has also attracted large crowds with his economic message, demonstrating a hunger within the party for an alternative to Clinton.
