“Wow! The DeSanctus TWITTER launch is a DISASTER! His whole campaign will be a disaster. WATCH!” he wrote on Truth Social.
The Florida governor’s campaign launch descended into chaos as Twitter crashed immediately as he tried to present his candidacy to Elon Musk.
“Rob,” My Red Button is bigger, better, stronger, and is working (TRUTH!), yours does not! (per my conversation with Kim Jung Un, of North Korea, soon to become my friend!)” Mr Trump wrote on Truth Social.
Mr Trump tweeted in January 2018 that the “nuclear button” in Washington DC was “much bigger and more powerful” than the North Korean dictator’s “and my button works!”
Meanwhile, Donald Trump Jr, the eldest son of the one-term president, took to Twitter to ridicule his father’s main rival for the GOP presidential nomination, branding the campaign launch a “DeSaster.”
“DeSantis is making JEB! look high energy right now,” he added.
The former president then posted two videos to Truth Social mocking Mr DeSantis. The first showed a Tesla rocket with “Ron” written over it crashing, while the second mixed clips of the chaotic twitter event with Mr Trump’s own campaign launch.
The Twitter event, which began at 6pm ET, was plunged into chaos when it was hit by tech issues and dropped audio almost immediately.
David Sacks, one of the moderators of the event, said the massive number of participants was “melting the servers”.
Despite the mocking he has received for the event, Mr DeSantis told Mr Musk as it ended: “We should do it again.”
Earlier he laid out why he was running for president, before mostly talking about right-wing culture war issues beloved by many of his supporters.
“I am running for president of the United States to lead our great American comeback,” Mr DeSantis said.
“American decline is not inevitable. It is a choice,” he said. “And we should choose a new direction, a path that will lead to American revitalization.”
