SAN FRANCISCO (AP) — Tesla CEO Elon Musk is apparently taunting the government agency that accused him of duping investors just days
after negotiating a settlement
to keep his job.

Musk jabbed the Securities and Exchange Commission on his Twitter account, the same agency that went after him for
an August 7 tweet
in which he declared he had secured financing for a Tesla buyout. The SEC alleged that Musk hadn’t locked up the estimated $25 billion to $50 billion that it would have required to pull off that deal.

In a
Thursday tweet
, Musk praised the “Shortseller Enrichment Commission” for “doing incredible work.”

Musk has long feuded with short sellers, a category of investors that have been betting on Tesla’s stock to fall.

Tesla shares declined 2 percent in extended trading after Musk’s tweet.
