In a reversal of its long standing policy, Twitter has locked the President of the United States’ Twitter account and forced the removal of three offending tweets.

“As a result of the unprecedented and ongoing violent situation in Washington, D.C., we have required the removal of three  @realDonaldTrump Tweets that were posted earlier today for repeated and severe violations of our Civic Integrity policy,” the site writes.
