Per BI:

Musk's $44 billion deal is headed toward a close at the end of next week, likely on Friday, two people familiar with the situation told Insider. Beyond that, the company's trajectory is murky, though Twitter will almost certainly see steep cuts to staff, including CEO Parag Agrawal and other top executives, people familiar with the deal said. These people spoke on condition of anonymity because they're not authorized to speak to press.

Officials in the Biden administration have discussed a security investigation into some of Musk's dealings, including his acquisition of Twitter, Bloomberg reported, but this is not seen as a genuine threat to the deal since there is no active investigation and one does not seem to be forthcoming, a person familiar with the deal said. A bigger problem could be that Musk had done "absolutely no" transitional work for his impending takeover, this person added.
