“You know what? He died,” Trump said of Schwarzenegger at a social media summit. “I was there.”

Schwarzenegger is the last Republican to be governor of California, leaving office in 2011.

“I’m still here. Want to compare tax returns, @realDonaldTrump?” Schwarzenegger responded.

The two have feuded in the past, with Trump often needling Schwarzenegger for the ratings decline “The Celebrity Apprentice” experienced under his stewardship and hitting him over his tenure as California governor.

“Yes, Arnold Schwarzenegger did a really bad job as Governor of California and even worse on the Apprentice...but at least he tried hard!” Trump tweeted in 2017.

Schwarzenegger responded to that broadside by sharing a news article featuring his disclosure of his tax returns.

Critics hammered Trump during his 2016 White House bid for being the first major-party presidential candidate in decades to refuse to release the returns. Trump has said in the past that he would make his returns public once the Internal Revenue Service finished auditing him.

But the IRS has said an audit does not preclude someone from making tax returns public.

Schwarzenegger declined to endorse Trump in the 2016 White House race.
