Three provided sources is amazing in backing up your claim, however if you're doing research and cannot prove a claim to be false or true you shouldn't claim it to be true. Even when the original claim is providing government sources. Those can be faked as well as any, using the SIFT method should work better when trying to decide if a source for a claim is true or false. Also don't trust news sites that post on 'X' because you cannot be sure who's behind the account and furthermore cannot prove the claim to be true.
