A rogue employee at Twitter Inc., on his or her last day, shut down President Trump’s Twitter page on Thursday evening, causing a major investigation at the publicly-held company, and sparking outrage among Trump supporters.

For an 11-minute span, the @realDonaldTrump Twitter page did not exist. That’s because the customer service representative deactivated the account.

“We are conducting a full internal review,” the company said in a tweet (see below).

It is unclear how a “customer support” worker had obtained clearance to deactivate such a high-profile account. The president has tweeted more than 36,000 times and has nearly 42 million Twitter followers.

When reports first surfaced about the outage, Twitter officials initially blamed “human error.”

Shortly before 7 p.m. Thursday, social media reports surfaced that Trump’s personal account, @realDonaldTrump, was unavailable, providing the error message that the user “does not exist.” The account was restored by 7:03 p.m.

But about two hours later, the company said the deactivation “was done by a Twitter customer support employee who did this on the employee’s last day.”

The company has, in the past, suspended other accounts for violating its terms and conditions. The company has resisted calls from those opposed to the president to delete his account.

Trump tweeted about the deactivation on Friday morning, stating, “My Twitter account was taken down for 11 minutes by a rogue employee. I guess the word must finally be getting out-and having an impact.”

“Google, Twitter & FB try to silence conservatives by deleting, demonetizing & restricting. But our message is bigger than the message board,” tweeted conservative host Dennis Michael Lynch.
