Every community has rules about what content is on topic, and if you post something else it will be removed. That's not censorship.
A government statement is a government statement. It is not news. A proper news organisation would, for example, fact check whatever statement the government made and consider if the reader should be given additional context - perhaps details the government might be omitting in order to increase their chances of being re-elected.
On an issue as politically charged as this one, it's especially important for the full journalistic process to be followed. You're essentially attempting to post to the community as if you are a journalist yourself. But you're not... and even if you were there's no team of people fact checking what you wrote.
There are communities where you can do that, but US News one one of those communities.
