The Insurrection Act: A History of Crisis and Control

There are few laws President Trump name-checks more frequently than the Insurrection Act.

A 200-year-old constellation of statutes, the act grants emergency powers to thrust active-duty soldiers into civilian police duty, something or else barred by federal law.

Trump and his team have threatened to invoke it almost daily for weeks – most recently on monday,after a reporter pressed the president about his escalating efforts to dispatch federalized troops to Democrat-led cities.

“Insurrection Act – yeah, I mean, I could do that,” Trump said. “Manny presidents have.”

Roughly a third of U.S. presidents have called on the statutes at some point – but history also shows the law has been used only in moments of extraordinary crisis and political upheaval.

The Insurrection Act was Abraham Lincoln’s sword against secessionists and Dwight D. Eisenhower’s shield around the Little Rock Nine, the young Black students who were the first to desegregate schools in Arkansas.

Ulysses S. Grant invoked it more than half a dozen times to thwart statehouse coups, stem race massacres and smother the Ku Klux Klan in its South Carolina cradle.

But it has just as frequently enough been wielded to crush labor strikes and strangle protest movements. The last time it was invoked, Defense Secretary Pete Hegseth was in elementary school and most U.S. soldiers had not yet been born.

Now, many fear Trump could call on the law to quell opposition to his agenda.

“The Democrats were fools not to amend the Insurrection Act in 2021,” said Kevin Carroll, former senior counsel in the Department of Homeland Security during Trump’s first term. “It gives the president almost untrammeled power.”

It also precludes most judicial review.

“It can’t even be challenged,” Trump boasted Monday. “I don’t have to go there yet, because I’m winning on appeal.”

If that winning streak cools, as legal experts say it soon could, some fear the Insurrection Act would be the governance’s next move.

“The Insurrection Act is very broadly worded, but there is a history of even the executive branch interpreting it narrowly,” said john C. Dehn, an associate professor at Loyola University Chicago School of Law.

The president first floated using the Insurrection Act against protesters in the summer of 2020. But members of his Cabinet and military advisors blocked the move, as they did efforts to use the National Guard for immigration enforcement and the military to patrol the border.

“They have this real fixation on using the military domestically,” carroll said. “It’s sinister.”

In his second term, trump has instead relied on an obscure subsection of the U.S. code to surge federalized soldiers into blue cities, claiming it confers many of the same powers as the Insurrection Act.

Federal judges disagreed. Challenges to deployments in Los Angeles, Portland, Ore., and Chicago have since clogged the appellate courts, with three West Coast cases before the U.S. 9th Circuit Court of Appeals and one pending in the 7th Circuit, which has jurisdiction over Illinois.

The result is a growing knot of litigation that experts say will fall to the Supreme Court to unwind.

as of Wednesday, troops in Oregon and Illinois are activated but can’t be deployed. The Oregon case is further complex by precedent from california, where federalized soldiers have patrolled the streets since June with the 9th Circuit’s blessing. That ruling is set to be reheard by the circuit on Oct. 22 and could be reversed.

Meanwhile, what California soldiers are legally allowed to do while th
