Impeachment is our system's last resort for someone who treats himself or herself as above the law, the most relevant thing is whether this president, by his recent course of action, on top of his violations of the foreign corruption or emoluments clause, this president has shone that he cannot be trusted to remain within the law and our constitution's last resort for situations of that kind is to get the person out of office.

When I visited North Korea in November 2014, is that Kim Jong-un is not merely the head of state of the DPRK - the Democratic People's Republic of Korea, North Korea - he's also their deity.

The Russians have to be celebrating with a minimal expenditure of resources and what they have accomplished.
