The Trump administration and Elon Musk’s Department of Government Efficiency have recently targeted an array of federal agencies from the Department of Education to the US Agency for International Development (USAID.)

Musk and his team have been focused on federal cash flows in the government as they look to streamline agencies and slash spending, as well as getting rid of diversity, equity and inclusion — known as DEI — in the federal workforce in compliance with President Donald Trump’s executive action.

Here’s what you should know about Trump’s agency changes:

Deferred resignation program: A Trump administration official familiar with the matter says at least 40,000 people have opted into the deferred resignation program ahead of a Thursday deadline that could soon leave many federal workers without a job.

Roughly 2 million federal employees received the offer, which allows workers to leave voluntarily and be paid through September 30 but not have to continue working.

An Office of Personnel Management (OPM) spokesperson says the number “is growing and OPM doesn’t plan to release deferred 

resignation numbers until after the deadline.”

Most employees at the Department of Commerce, including the National Oceanic and Atmospheric Administration and the National Weather Service, received an email about the so-called federal employee buyout Monday afternoon, CNN previously reported. One official warned that lower staffing at these agencies could negatively impact the ability to disperse life-saving weather warnings to communities during natural disasters.

A series of removals: Erica Roach, OPM’s chief financial officer, was pushed out this week, two sources with knowledge of the situation told CNN.

David Lebryk, the top civil servant at the Treasury Department, left unexpectedly last week after Trump-affiliated officials expressed interest in stopping certain payments made by the federal government, according to three people familiar with the situation.

Dismantling USAID: Over the last two weeks, the Trump administration has made significant changes to the USAID, the agency charged with delivering humanitarian assistance overseas, including dozens of senior officials put on leave, thousands of contractors laid off and a freeze put on billions of dollars in humanitarian assistance to other countries.

On Wednesday, five former leaders of the agency across Republican and Democratic administrations spoke out against the Trump administration’s attempts to dismantle it and called on “Congress to swiftly protect the Agency’s statutory role.”

Democrat’s plans to counter Trump: Democratic lawmakers are mapping out a “coordinated effort” to counter the moves by Trump, including those to restructure the federal government and its workforce.

According to Democratic Sen. Tim Kaine, “there’s a litigation strategy, a state court strategy, a legislative strategy in Congress, and a political strategy” to counter the president’s actions.

The chief financial officer of the Office of Personnel Management (OPM), which manages more than $1 trillion in funds, was pushed out this week, two sources with knowledge of the situation told CNN.

Her departures is the latest in a series of top career officials who have been removed from their jobs atop federal agencies by Trump political appointees working in coordination with Elon Musk’s Department of Government Efficiency effort.

The CFO, Erica Roach, was asked last week in a meeting with a Trump political appointee if she was someone they could “trust” and if she was “loyal,” according to one of the sources.

The source said Roach responded that she “always” does “the right thing.” Roach was not given a reason for why she was removed from her role but rather offered another position that would have been a demotion, the source said. She chose to resign instead.

Federal shake-up: Musk and his team have been focused on federal cash flows in the government as they look to streamline agencies and slash spending. At the Treasury Department, the top civil servant David Lebryk, left unexpectedly last week after Trump-affiliated officials expressed interest in stopping certain payments made by the federal government, according to three people familiar with the situation.

“The only way to stop fraud and waste of taxpayer money is to follow the payment flows and pause suspicious transactions for review. Obviously,” Musk posted on his social media platform X on Monday.

OPM did not respond to a request for comment.
