By Andrea Shalal, Leah Douglas, Ahmed Aboulenein and Ted Hesson WASHINGTON (Reuters) -Almost half of the probationary workers at the U.S. Centers for Disease Control and Prevention and others at the National Institutes of Health are being forced out as President Donald Trump overhauls government agencies,

Department of Health and Human Services officials expected most of the agency’s roughly 5,200 probationary employees to be fired.

The Trump administration is laying off 1,300 employees at the Centers for Disease Control and Prevention, shrinking the public health agency as part of an effort to cut costs across the federal government.
