NIH officials involved in writing a paper in 2020 about the origin of SARS-CoV-2 actively suppressed consideration of a lab leak hypothesis and exaggerated the evidence for a natural origin. Some of their communications have been released and others involved have testified to that under oath.
But your second link contradicts this story entirely! It's about a claim from the CDC director that other officials in other agencies froze him out because he wanted to consider the lab leak hypothesis.
Sorry I should have been more clear. From a US federal government perspective, the fault for the sloppy science in the 2020 paper lies with the NIH and not the CDC. Will edit my comment above.
