A President has the power to make a recess appointment, and we’ve supported Mr. Obama’s right to do so. The Constitutional catch is that Congress must be in recess.
The last clause of Section 5 of Article 1 of the Constitution says that “Neither House” of Congress can adjourn for more than three days “without the Consent of the other” house. In this case, the House of Representatives had not formally consented to Senate adjournment. It’s true the House did this to block the President from making recess appointments, but it is following the Constitution in doing so. Let’s hear Mr. Obama’s legal justification.
