Trump has frozen all travel and communications at the Department of Health and Human Services, including the CDC and the National Institutes of Health

The Trump administration ordered an immediate pause on public communications from federal health agencies like the CDC, FDA, and NIH. The U.S. Department of Health and Human Services (HHS) says it expects the pause to be temporary.

Federal health officials have been instructed to temporarily stop any “external communications” to the public, according to two officials with knowledge of the situation.

Meetings designed to distribute grant money to fund research were canceled as part of a communications freeze at health agencies.

A new memo by NIH Acting Director Matthew Memoli, obtained by Forbes, clarifies what can and can’t be done with regard to clinical trials, purchasing, research and the like.

Despite concerns about the future of research at the National Institutes of Health, current clinical trials can continue as scheduled, the agency’s acting director told staff scientists in an email Monday.
