The video also highlights when Biden said at an event in Iowa that "poor kids" are "just as talented as white kids." He then corrected himself and said, "wealthy kids."

Biden is the front-runner in the Democratic race polls. The former vice president is now 76, and if elected he would be 78 years old by the time of his swearing in 2021, making him the oldest person to occupy the White House.

Trump has gone after Biden's age before, previewing a line of attack should Biden win the nomination.

Meanwhile, fellow 2020 Democratic rival Julián Castro, the former Housing and Urban Development Secretary, came under scrutiny last week with a jab at Biden that many saw as a dig at his age.

“Are you forgetting what you said just two minutes ago?” Castro asked Biden, during a moment of the primary debate.

Castro has denied his comment was referring to Biden's age.
