From The New York Times:
YouTube said on Tuesday that it had suspended President Trump’s channel over concern about “ongoing potential for violence,” the latest move by one of the large technology companies to limit the president online.
In a post on YouTube’s official Twitter account, the Google-owned video site said it had suspended Mr. Trump’s account after one of his recent videos violated its policy for inciting violence. That meant Mr. Trump would not be able to upload new content to his channel, which had about 2.8 million subscribers, for at least seven days. YouTube also said it was disabling all comments on his channel indefinitely.
