What is happening with bird flu experts in the Trump administration?

According to NBC News reporting, the Trump administration has fired bird flu experts at the USDA, which they are now trying to rehire. Rachel Maddow sarcastically characterizes this as an accidental firing with the administration claiming they 'didn't mean to' let these experts go. This incident appears to be part of a pattern, as Maddow mentions similar staffing reductions at the National Nuclear Security Administration. These personnel decisions affecting experts in critical public health and safety roles highlight a concerning trend of disruption in important government functions.
