The U.S. Department of Agriculture responded on Wednesday to reports claiming the agency’s former inspector general was forcibly removed from her office after resisting her dismissal from the Trump administration.

The full scope of the Friday night mass firings was coming into sharper view as one fired watchdog official warned of “a never-ending cycle of politicization.”

The USDA Inspector General deals with food safety, audits and investigations of the Agriculture Department and violations of animal welfare laws. The USDA has been one of the main agencies dealing with the outbreak of bird flu, which has spread to cattle and poultry. One person in Louisiana has died from the disease.
