UPDATED: President Trump’s account was taken down by a rogue employee on his or her last day of employment Thursday, and remained offline for 11 minutes. Twitter revealed the cause of the outage late Thursday, and said that a review of the incident was ongoing.

Through our investigation we have learned that this was done by a Twitter customer support employee who did this on the employee’s last day. We are conducting a full internal review. https://t.co/mlarOgiaRF — Twitter Government (@TwitterGov) November 3, 2017

Trump’s account, which boasts 41 million followers, was down at about 3:50 p.m. PT on Thursday, and returned by 4:00 p.m. PT. The message that surfaced on Trump’s account, however, wasn’t the one that typically surfaces when an account is suspended for a terms of services violation.

Twitter initially said that the take-down was caused by “human error.”

Earlier today @realdonaldtrump’s account was inadvertently deactivated due to human error by a Twitter employee. The account was down for 11 minutes, and has since been restored. We are continuing to investigate and are taking steps to prevent this from happening again. — Twitter Government (@TwitterGov) November 3, 2017

Trump had tweeted as recently as 3:35 p.m. PT, sharing a video of him formally nominating Jerome Powell as Chairman of the Federal Reserve.

The President had recently drawn ire for his tweets about the Manhattan terror attack. He tweeted on Wednesday that Sayfullo Saipov, the man charged with two terrorism counts in the shooting, “should get the death penalty.” Experts told NBC News that his tweets could make it harder for prosecutors in the case against Saipov.

In the past, campaigns have been launched for Twitter to take action against Trump’s account for apparently violating its rules. Twitter was forced to comment on the backlash in September, after Trump tweeted, “Just heard Foreign Minister of North Korea speak at U.N. If he echoes thoughts of Little Rocket Man, they won’t be around much longer!”

“Among the considerations is ‘newsworthiness’ and whether a tweet is of public interest,” the policy team wrote in a statement at the time. “This has long been internal policy and we’ll soon update our public-facing rules to reflect this.”

The official @POTUS account, which mostly consists of retweets from @realDonaldTrump, was unaffected.

Update: 8pm: This post was updated with Twitter’s latest statement.
