Elon Musk — the eccentric billionaire and CEO of Tesla — is inching closer and closer to purchasing Twitter as the regulatory waiting period for completing the purchase under the Hart-Scott-Rodino Antitrust Improvements (HSR) Act of 1976 officially expired on Friday.

The HSR Act requires companies to give advance notice of transactions above a certain threshold to the Federal Trade Commission (FTC) and the Department of Justice (DOJ). The FTC and DOJ subsequently have 30 days from the initial notification of the intended purchase to pursue an investigation of the transaction to determine whether any additional information is needed to assess the legality of the purchase.

Fox Business reported that neither the FTC nor DOJ requested additional information from Musk or any of his affiliated companies.
