Former Vice President Joe Biden is ready to throw his hat into the 2020 president race -- but only if President Donald Trump is the Republican nominee, according to a report.

Fox Business correspondent Charles Gasparino reported on Thursday that Biden had told friends on Wall Street that he was preparing for a presidential bid. But according to the sources, Biden will only enter the race if President Donald Trump runs as the GOP pick.

"He's going to his Wall Street friends/associates, he has a lot of connections there -- people that would raise money for him -- and saying, 'Listen, I am seriously considering running for president, but only if one candidate runs," Gasparino told Fox Business host Neil Cavuto.

Gasparino noted that Biden will be nearly 78 in 2020. Trump will be 74 when the next election occurs.

"He said the age difference between he and Trump is not that great, age won't be an issue," the Fox Business reporter explained. "He is actually saying this. He's going around to Wall Street guys. And by the way, Wall Street guys always liked Biden."
