The Trump campaign coordinated with the Russians BEFORE the recent election. Yesterday evening, Rachel Maddow disclosed that US intelligence agencies have evidence that the Trump campaign coordinated with the Russians before the recent vote that put Trump in the White House. That should lead to the removal from office of both Trump and Pence.
Next in line of succession is Paul Ryan, who is not an acceptable choice for President of the US, in my opinion. However, I would be willing to accept Ryan as President in a government of national unity if his Vice President is an experienced Democrat. Either Hillary Clinton or Bernie Sanders would be acceptable.
