Union leaders criticized both parties in Congress but also targeted Trump, accusing him of using federal workers as “political pawns” after warnings Tuesday that back pay is not guaranteed.

“He intends to either violate the law, or degrade, frighten, antagonize hardworking federal employees whose only crime is caring and wanting to work for the American people,” said Randy Erwin, president of the National Federation of Federal Employees.
