national forest to loggers. >> got to take care of the floors, you know, the floors of the forest, very important. >> when "all in" starts right now. >> good evening from new york. i'm chris hayes there is a case to be made that there is a loaded gun embedded in the constitution, and that loaded gun is the pardon power. just sitting there, waiting to be abused. it's a power given solely to the president, and it would theoretically allow for all kinds of misuse. for example, what if a really, really violent genuinely fascist president ordered his chief of staff to murder the head of the opposition party on federal property and then pardoned him? what are you going to do? the only constitutional solution is impeachment but if his party controls the senate and they stick with him. the pardon power is a way of undoing the entire structure of the rest of the constitution, which is what can make it so dangerous if abused. we've seen it surface in impeachment proceedings before in the case of richard nixon.
