Mike Pence (R-IN), along with a group of rogue congressmen, is planning to go to Copenhagen to "derail Democratic efforts to negotiate an international climate agreement" -- basically, the Party of No is going international. And according to Mr. Pence:

President Barack Obama, Pence added, should refrain from negotiating treaties "in the absence of a national consensus."

... which is an interesting interpretation of Article II on the Constitution, which say of presidential powers:

He shall have power, by and with the advice and consent of the Senate, to make treaties, provided two thirds of the Senators present concur;

Checking, double-checking, and even triple-checking. Nope. Doesn't say a thing about seeking a national consensus as defined by what a right-wing, obstructionist congressman from Indiana says.
