This vacancy pre-dated the recess and was already under consideration by the Senate, and Cordray could not clear the hurdles. Obviously, the Senate thought there was no emergency or hurry. They left on vacation.
Unconstitutional because it was not a "happen during recess" issue.
Unconstitutional because the original constitution, with long periods for travel and communication, set this up for emergency vacancies, which this was not.
Unconstitutional because Cordray, even in a recess, cannot be "appointed". He could only be given a commission that automatically expires at the end of the Congressional session.
Excellent post. Contact our Senators and demand they shut down business.
