Musk says all US government staff must justify their work or lose jobs

Elon Musk, the advisor to Donald Trump, said Saturday that all US federal employees must justify their work or lose their jobs, hours after the president pushed him to be "more aggressive" in slashing government spending. Musk, the world's richest person and Trump's biggest donor has led the effort to fire swaths of the government workforce.

The email came from the US Office of Personnel Management (OPM), with the subject line "What did you do last week?”. The deadline to reply was 11:59 pm Monday, though the message did not say failure to do so would lead to termination. The American Federation of Government Employees (AFGE), the largest federal employee union, vowed to challenge any unlawful terminations in a statement from national president Everett Kelley.
