Senate Democrats are calling on the Trump administration to provide information on how many military veterans have been caught up in its federal workforce firing spree.

Sen. Mark Kelley of Arizona and 11 other Senate Democrats sent a letter to Charles Ezell, the acting director of the Office of Personnel Management, requesting a complete breakdown of all the buyouts offered and a list, by agency, of the federal employees who have received pink slips, including military veterans.

“More than 640,000 veterans were part of the federal workforce before Elon Musk and President Trump’s haphazard layoffs began, many of whom are losing their livelihoods after these layoffs and a legally questionable deferred resignation program,” the Democratic senators said in the letter.

“We are alarmed because it does not appear OPM conducted any meaningful assessment of how layoffs and the legally questionable ‘Fork in the Road’ deferred resignation offer would impact veterans,” they said. “We request information on what, if any, assessment OPM conducted on the impact the deferred resignation offer and mass layoffs will have on federal agencies’ ability to meet their missions and Congressional mandate, or the impact to the federal workforce, particularly on U.S. veterans.”

At least 100,000 federal ​employees have taken buyouts or been fired​, as the Department of Government Efficiency seeks to ​downsize the government’s 2.3 million-strong civilian ​workforce. The effort is ongoing, with thousands more layoff notices sent out in recent days to agencies such as the Education Department.

Mr. Trump has touted Mr. Musk’s work in seeking to eliminate waste, fraud and abuse in the federal government as a success story.

However, Democrats have criticized how Mr. Musk and his Department of Government Efficiency have sought $1 trillion in spending cuts.

They say the haphazard nature of the cuts fail to consider the impact on the vital work of the government and are upending the lives of working-class Americans of all political stripes.

Democrats have invited some federal workers as guests to Mr. Trump’s first address to a joint session of Congress since being elected in November.

Democrats have put a significant focus on the impact the federal layoffs and deferred resignation offers have had on military veterans. They have pointed to OPM statistics showing veterans comprised 30% of the federal workforce and 6% of the civilian workforce.

“All federal employees deserve fair treatment and recognition for their service to the American people,” the Democratic senators said. “Veterans bring great value and skill sets earned through their military service to the federal government.”

“To lay them off with no forethought is disrespectful to their service and damaging to our federal government,” they said.
