Donald Trump has handed a top White House role to a 23-year-old university student, according to reports in the US.

James Bacon, a student at George Washington University, will take over the role of director of operations for the Presidential Personnel Office (PPO) - the body which approves and determines selections for presidential appointments.

Bacon, who Politico said worked in the department of transportation alongside his studies, takes over from Katja Bullock, who served through both Bush and Reagan presidencies.

Bullock is more than 50 years older than Bacon.

He also reportedly took time out of his studies to work as a liaison in the department of housing and urban development, meaning he will graduate later than initially expected.
