For responding to a president who defies his constitutional limits, Congress is said to possess four powers: to impeach, to defund, to investigate, and to withhold confirmation of nominees.

But there is a fifth recourse, which the new Republican Congress might consider in view of President Obama’s executive amnesty for illegal immigrants: the power to censure. In fact, censure could work in tandem with Congress’s other powers, helping the legislature make the moral case for responding to the president’s lawlessness.
