CDC Director Rochelle Walensky Resigns Amid Pandemic Transition.

Rochelle Walensky, the director of the Centers for Disease Control and Prevention (CDC), has announced her resignation, effective June 30. Walensky played a key role in the Biden administration's response to the Covid-19 pandemic and has been the agency's director for a little over two years. The announcement came as the World Health Organization said Covid is no longer a global emergency. Walensky did not explain exactly why she was stepping down, but said the nation was at a moment of transition as emergency declarations come to an end.
