Status: in effect, as of 2026-09-22.

What we don't know: The full list of CDC documents altered by HHS political appointees, and which specific public statements resulted, was not fully detailed in the sources reviewed.

Reporting in 2020 found that political appointees at the Department of Health and Human Services rewrote or edited the Centers for Disease Control and Prevention's public coronavirus guidance and its weekly scientific bulletin before release, bypassing the agency's normal scientific review.¹²³⁴

Where: United States
Level of government: National
Tactic: Prior restraint
Stage: Restrict (see the ladder)
Head of government at the time: Donald Trump
Issue of the day: The reporting concerned the CDC's coronavirus testing guidance and its weekly Morbidity and Mortality Weekly Report during the summer and fall of 2020, as the Trump administration sought to align public messaging with the president's own statements about the pandemic.
Outcome: Unknown. No agency reversal of the practice was documented in the sources reviewed; a congressional investigation examined the interference without a public admission of wrongdoing.
Era: The 2020s

What happened

Reporting published in September 2020 found that Michael Caputo, an HHS spokesperson, and an adviser he brought in, Paul Alexander, sought to change or delay CDC scientific communications, including the agency's weekly Morbidity and Mortality Weekly Report, so that public messaging would not conflict with statements President Trump had made about the pandemic. In one instance, HHS staff rewrote CDC coronavirus testing guidance and published it on the CDC's own website without the agency's normal scientific review, a document CDC officials later said did not reflect the views of many scientists inside the agency. Assistant Secretary Brendan Giroir said he coordinated input from task-force scientists but told reporters he did not know why some edits bypassed the standard review process. The episode became the subject of a congressional oversight investigation into political interference at the CDC during the pandemic.¹²³⁴

What reason was given

Caputo told colleagues his goal was to "execute the president's agenda and to knock down any messaging, any communications that were seen as conflicting with what President Trump was saying about coronavirus."¹

What changed for reporting

Reporters covering the pandemic received CDC guidance and public statements that outside scientists said had been shaped by political appointees rather than by the agency's own scientific review, undercutting the reliability of official public health communications reporters relied on.²³
