(Reuters) - Twitter Inc on Tuesday placed a warning notice on a tweet by President Donald Trump threatening "serious force" against protesters in the U.S. capital, the second time it has used the label since it began challenging Trump's tweets in May.
"There will never be an 'Autonomous Zone' in Washington, D.C., as long as I'm your President. If they try they will be met with serious force!" the president said in his tweet, which Twitter said violated its policy against abusive behavior.
