Actually it appears that the scientists were allowed to issue this one.

The Centers for Disease Control and Prevention (CDC) on Friday revised controversial guidance that previously stated people without COVID-19 symptoms don’t necessarily need to be tested.

In updated guidance, the agency said: “If you have been in close contact, such as within 6 feet of a person with documented SARS-CoV-2 infection for at least 15 minutes and don’t have symptoms you need a test.”

“Please consult with your healthcare provider or public health official. Testing is recommended for all close contacts of persons with SARS-CoV-2 infection,” the CDC added.

The agency faced significant backlash from public health officials, local health departments and members of Congress when it changed its guidance last month to state that people without symptoms “don’t necessarily need a test” even if they have had close contact with confirmed cases.

That language was deleted Friday and replaced with new text under a “clarifications” heading.

“Due to the significance of asymptomatic and pre-symptomatic transmission, this guidance further reinforces the need to test asymptomatic persons, including close contacts of a person with documented SARS-CoV-2 infection,” the clarification reads.

Public health experts warned that the CDC’s changes last month would be a step backward in the nation’s COVID-19 response.

I posted yesterday that those guidelines about skipping testing were actually written by DHS with no input from the CDC scientists. 

After that was made public we suddenly get this about-face, which my friends illustrates, quite effectively, the power of the media.
