A digital communication via tweet is the same as recording and archiving what is said on tv. Keep the tweets and have constant investigations into them on whether they are True, like clinton's emails. Fair is fair. They seem to be the best evidence of his character, which is demeaning, demoralizing, disrespectful and a constant liar. They were also used in a recent court case. We will need these for impeachment trials, future court cases when he does yet another stupid thing and so that kids can learn what not to become when they learn history. These should be used in campaigns against bullying to educate people too.
