President Elect Donald Trump has created a new government advisory group – the Department of Government Efficiency or ‘DOGE’ - to help cut the US budget. The world richest man, Elon Musk, will co-head the department and has pledged to cut ‘at least $2 trillion’ to ‘balance the budget’. But is this possible? We talk to Professor Linda Bilmes about what DOGE could or couldn’t do and how she balanced the budget in the 1990’s.
