"How did Schumer no[t] know that the security services would go after Trump?"
Answer:
He did know. Because Trump takes gets his strategic advice from Vladimir Putin. Trump admits this openly.
Opinion: He's a friggin mole who is probably too friggin stupid to fully realise it. Then again most of his back door finance comes from oligarchs linked to Putin. Once he is booted this case will explode around those Republicans who now openly betray their country.
Bolton is today accusing Trump of misleading the US public over NK. Yesterday there were anti-Trump articles being published by the Mormons.
Reality: The GOP will dump Trump the moment they sense the wave against him will lead to an electoral loss. There is no loyalty in anyone's party politics.
