2. I think those are not his tweets. The staff is doing the political strategy tweeting.

Trump is too demented to do the truly coherent stuff with proper grammar and spelling that tweets from his account. The Obama cyber lynching started after the grand jury subpoenaed WH records, and was a carefully laid out strategy to attack the investigation as apolitical witch hunt by the Obama administration. Trump is incapable of that level of reasoning, it is more characteristic of his legal staff and strategists developing a defense in a case where they know they have been caught and the evidence will convict them, so they need ti impugn the evidence.
