WASHINGTON (Reuters) -The State Department has kicked off a second round of the deferred resignation program, according to an internal email seen by Reuters and two U.S. officials, as part of President Donald Trump's push to ensure that the agency and its workforce are in line with his "America First" agenda. The internal email dated April 25 comes days after U.S. Secretary of State Marco Rubio described the Department as "bloated, bureaucratic" and proposed to eliminate more than 100 bureaus and offices and plan towards reducing staff by 15%. The Department's planned overhaul is the latest in an unprecedented push by Trump and his billionaire advisor Elon Musk to significantly shrink the federal government due to what they say is its wasteful spending of U.S. taxpayer money.
