The SEC has reportedly shifted its Tesla investigation into high gear, Fox Business reports, sending subpoenas to the California-based automaker regarding its potential plans to go private. The subpoenas are intended to help the SEC determine whether or not Musk's tweets and blog posts "intentionally misled investors." Fox Business says that this means the investigation has moved into a more formal phase.

It's unclear what happens next in the SEC's investigation, but then again, nearly every inch of this situation is pretty unclear.
