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.<br /><br />Court filings made public on Monday suggested that Epstein may have introduced Musk as a client to JPMorgan.<br /><br />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.<br /><br />"The notion that I would need or listen to financial advice from a dumb crook is absurd," Musk said.
