Elon Musk’s Department of Government Efficiency has been Donald Trump’s battering ram during the president’s first 100 days, slashing the federal government and trying to bend its remnants to Trump’s will.

Elon Musk's Department of Government Efficiency (Doge) - set up to cut US government spending - claims to have saved, on average, more than $10bn a week since President Trump entered office. "We're talking about almost $200bn and rising fast," Trump told the BBC when talking about Mr Musk's cost-cutting drive on 23 April.

Musk’s departure from the Department of Government Efficiency comes amid layoffs, political backlash, and a push to revitalize Tesla’s AI ambitions.
