While our country guarantees freedom of speech (though clearly the new administration is against freedom of speech for scientists or freedom of the press), private companies can hold individuals responsible for their speech. It is within Twitter's rights as a private company to shutdown the Twitter accounts tied to President Donald Trump. 

 Donald Trump uses Twitter in an unreasonable manner to announce possible policies that have not been carefully considered. This is a threat to businesses, the global economy, and US national security. He has already proven his ability to affect the stock market through his tweets. Lockheed, Boeing, and Toyota have all been financial victims of his tweets. 

More importanly Trump's irresponsible use of Twitter could result in war with a foreign power. His lack of diplomacy is evident. 

Twitter, as a responsible business, should not allow their private platform to be used to start a war. Stop the threat, Stop Trump from tweeting buy shutting down his accounts!
