Vice President Joe Biden is "talking to friends, family and donors" about entering the 2016 presidential race, according to The New York Times. He's been holding meetings and may be seriously considering taking on Democratic frontrunner Hillary Clinton for the top job.

Insiders say that Biden's son Beau was very supportive of his father's presidential aspirations. Beau encouraged Biden to run again before his death earlier this year. Biden, 72, has served as the Vice President of the U.S. since 2008 after losing the primary election to Barack Obama.

Hillary Clinton has been considered to be the Democratic frontrunner in the upcoming presidential race for the last few years after losing the primary election to Obama in 2008 and being appointed Secretary of State. However, looming questions surrounding her role in the Benghazi attack, and her use of emails regarding that event has made some donors shy, reported The New York Times.

"It's not that we dislike Hillary, it's that we want to win the White House," lawyer and Democratic donor Richard A. Harpootlian said.

There are a total of five Democratic candidates vying for the primary as of Saturday. In addition to Clinton, they are Sen. Bernie Sanders (Vt.), former Gov. Martin O'Malley (Md.), Sen. Jim Webb (Va.) and Sen. Lincoln Chafee (R.I.). Hillary Clinton is polling around 55 percent as of Thursday. Joe Biden, though still undeclared, is polling at 13 percent, The Telegraph reported.

"As the Biden family continues to go through this difficult time, the Vice President is focused on his family and immersed in his work," Kendra Barkoff, a spokeswoman for Biden, said in a statement, according to ABC News.
