Probably you are correct, but there are some details in the Ken Harris tweet that don’t correspond to the October regulatory action. This article has a link at the end to the action in the CFR https://www.biopharmadive.com/news/us-tightens-scrutiny-of-foreign-investment-into-biotech-sector/539437/ For example, the CFR says comments are due November 10 while the tweet says December 18. A reply to the tweet asked for the source, no response to that yet.
