President Donald Trump’s budget office rescinded an order freezing spending on federal grants, less than two days after it sparked widespread confusion and legal challenges across the country, according to two people familiar with the matter.

Agencies should aim for a 30-day deadline to implement Trump’s return-to-office executive order, according to a memo from the Office of Personnel Management.

Senator Tim Kaine, Democrat of Virginia, quickly condemned the Trump administration’s offer to roughly 2 million federal employees to resign in exchange for pay, saying in a Senate floor speech that the deal was a trick, that the president didn’t have the authority to make the offer and employees who resign may not be paid.
