What unexpected situation occurred with bird flu experts during the Trump administration?

According to NBC News, the Trump administration accidentally fired experts working on bird flu at the USDA. This appears to have been an unintended action, with Rachel Maddow sarcastically noting they "totally didn't mean to fire" these specialists. The administration is now reportedly attempting to rehire these experts after recognizing the error. This incident follows a similar pattern with the National Nuclear Security Administration, which Maddow had discussed previously. These actions represent concerning lapses in maintaining expertise in critical public health and safety areas, particularly regarding pandemic preparedness during a time of heightened concern about infectious diseases.
