Responding to the development, press secretary Karoline Leavitt told NBC News: "We are grateful to the judge for extending the deadline so more federal workers who refuse to show up to the office can take the administration up on this very generous, once-in-a-lifetime offer.".
A federal judge has temporarily blocked Donald Trump's plan to get rid of government employees by offering them a payout.
The US outlet also reported that the number of federal employees who had accepted the controversial buyout offer had hit 60,000, citing a senior administration official.
US district judge George O'Toole Jr, in Boston, did not express an opinion on the legality of the programme but scheduled a hearing for Monday at 2pm local time (10am in the UK).
The ruling came hours before the midnight deadline for workers to apply for the deferred resignation program - which has been commonly described as a buyout.
