President Donald Trump's @realdonaldtrump Twitter account was "inadvertently deactivated" by a Twitter Inc. employee Thursday and was down for 11 minutes before it was restored, the social media company said. "Earlier today @realdonaldtrump's account was inadvertently deactivated due to human error by a Twitter employee," the company said in a tweet. "We are continuing to investigate and are taking steps to prevent this from happening again," it added. A Twitter representative declined to comment further. The White House did not immediately respond to a request for comment. Trump has made extensive use of messages on Twitter to attack his opponents and promote his policies, both during the 2016 presidential campaign and since taking office in January. He has 41.7 million followers on Twitter. His first tweet after Thursday's outage: In a similar incident last November, Twitter Chief Executive Officer Jack Dorsey's account was briefly suspended as a result of what he said was an internal mistake.
