The CDC is totally free to do studies. What it was prohibited from doing is propaganda after it was caught doing that during the Clinton administration.

The “CDC had their hands tied to prevent any studies on gun violence” comes from the same Bloomberg source as this article, it is not accurate, and is plain propaganda.

The outgoing president in fact had the CDC do a study. It did not support the gun control agenda, and in places contradicted it.

Ergo, no more studies.

This gets into politics which I really think is outside the scope of the discussion.
