Trump announced he was launching a new media company, Trump Media & Technology Group, and its “Truth Social” app on Wednesday. The “Truth Social” app will begin a beta launch for “invited guests” in November, with a nationwide rollout planned for early 2022, according to a press release.

But people were able to sign up to create accounts using a publicly available link, Drew Harwell, a technology reporter for The Washington Post, said on Twitter late on Wednesday.

“I literally just registered ‘mikepence.’ The site hasn’t even launched yet and it’s already this vulnerable,” Harwell added. In a subsequent tweet, he revealed that account had been suspended.

In another tweet, Harwell said it appeared the “donaldjtrump” account on Truth Social had been hacked. A screenshot Harwell shared showed the pinned post on the account was of a defecating animal.
