Tesla and SpaceX CEO Elon Musk was served with a subpoena last month by the U.S. Virgin Islands in connection with the government's lawsuit against JPMorgan Chase over the financial services giant's potential involvement in sex offender Jeffrey Epstein's activities.

Court filings made public on Monday suggested that Epstein may have introduced Musk as a client to JPMorgan.

Responding to the development, Musk tweeted that this is "idiotic on so many levels." Calling the now-deceased Epstein a "cretin," the billionaire said the former never advised him on anything whatsoever.

"The notion that I would need or listen to financial advice from a dumb crook is absurd," Musk said.
