What the President Could Do If He Declares a State of Emergency

In the weeks leading up to the 2018 midterm elections, President Donald Trump reached deep into his arsenal to try to deliver votes to Republicans.

Most of his weapons were rhetorical, featuring a mix of lies and false inducements—claims that every congressional Democrat had signed on to an “open borders” bill (none had), that liberals were fomenting violent “mobs” (they weren’t), that a 10 percent tax cut for the middle class would somehow pass while Congress was out of session (it didn’t). But a few involved the aggressive use—and threatened misuse—of presidential authority: He sent thousands of active-duty soldiers to the southern border to terrorize a distant caravan of desperate Central American migrants, announced plans to end the constitutional guarantee of birthright citizenship by executive order, and tweeted that law enforcement had been “strongly notified” to be on the lookout for “ILLEGAL VOTING.”

These measures failed to carry the day, and Trump will likely conclude that they were too timid. How much further might he go in 2020, when his own name is on the ballot—or sooner than that, if he’s facing impeachment by a House under Democratic control?

More is at stake here than the outcome of one or even two elections. Trump has long signaled his disdain for the concepts of limited presidential power and democratic rule. During his 2016 campaign, he praised murderous dictators. He declared that his opponent, Hillary Clinton, would be in jail if he were president, goading crowds into frenzied chants of “Lock her up.” He hinted that he might not accept an electoral loss. As democracies around the world slide into autocracy, and nationalism and antidemocratic sentiment are on vivid display among segments of the American populace, Trump’s evident hostility to key elements of liberal democracy cannot be dismissed as mere bluster.

It would be nice to think that America is protected from the worst excesses of Trump’s impulses by its democratic laws and institutions. After all, Trump can do only so much without bumping up against the limits set by the Constitution and Congress and enforced by the courts. Those who see Trump as a threat to democracy comfort themselves with the belief that these limits will hold him in check.

But will they? Unknown to most Americans, a parallel legal regime allows the president to sidestep many of the constraints that normally apply. The moment the president declares a “national emergency”—a decision that is entirely within his discretion—more than 100 special provisions become available to him. While many of these tee up reasonable responses to genuine emergencies, some appear dangerously suited to a leader bent on amassing or retaining power. For instance, the president can, with the flick of his pen, activate laws allowing him to shut down many kinds of electronic communications inside the United States or freeze Americans’ bank accounts. Other powers are available even without a declaration of emergency, including laws that allow the president to deploy troops inside the country to subdue domestic unrest.

This edifice of extraordinary powers has historically rested on the assumption that the president will act in the country’s best interest when using them. With a handful of noteworthy exceptions, this
