President Donald Trump signed a new executive order that will limit federal hiring.The order says that federal agencies can only hire one employee for every four employees that leave.Agency heads will have to work with Elon Musk's DOGE to reduce their staff, the order added.President Donald Trump moved ahead with his goal of reducing the size of the government on Tuesday when he signed a new executive order to limit federal hiring.The order said that each federal agency can "hire no more than one employee for every four employees that depart."The restriction will not apply to positions related to public safety, immigration enforcement, or law enforcement. It will take effect upon the expiration of the 90-day hiring freeze that Trump imposed on the federal workforce when he took office on January 20.The order also said that agency heads will have to work with Elon Musk's Department of Government Efficiency, or DOGE, to reduce the size of the federal workforce."There are too many federal employees. Excluding active-duty military and Postal Service employees, the federal workforce exceeds 2.4 million," the White House said in a fact sheet about the order that was published on Tuesday.Speaking alongside Trump at the Oval Office, Musk said DOGE's cuts were "just common sense.""The people voted for major government reform and that's what people are going to get," Musk said on Tuesday.Representatives for the White House and DOGE did not respond to requests for comment from Business Insider.Trump has been stepping up on his efforts to shrink the federal workforce since the start of his second term.Last month, the Trump administration gave federal employees from January 28 to February 6 to accept a buyout offer. The offer was given to all federal employees except those working in military, postal, immigration, and national security roles.Last week, US District Judge George O'Toole Jr. extended the buyout deadline till Monday. O'Toole Jr. said during a court hearing on Monday that he will continue to pause Trump's buyout plan until he rules on its legality.A spokesperson for the Office of Personnel Management said on Monday that over 65,000 employees have accepted the offer. The OPM oversees the federal workforce.
