The Ugly History of the Law Used to Target Mahmoud Khalil

From the moment the McCarran-Walter Act was passed in 1952, The Nation has sounded the alarm about the danger it posed to politically active immigrants.

Donald Trump and his advisers have cited the Immigration and Nationality Act of 1952, also known as the McCarran-Walter Act, to justify the arrest and deportation of Palestine solidarity activists like Mahmoud Khalil. Without supplying evidence that Khalil has ties to Hamas, the administration argues that an obscure provision in the law allows “any aliens or class of aliens” to be deported if their presence is deemed to have “potentially serious adverse foreign policy consequences.”

Pat McCarran, one of the act’s coauthors, was a conservative Democratic senator from Nevada and a known racist and antisemite whose disregard for civil liberties was consistently condemned by this magazine. His Internal Security Act of 1950 required communists to register with the federal government and established a board to investigate those accused of subversive activities. “This was the year of the McCarran act,” The Nation observed, “a year in which fear spread poison on all levels of American life.” Reporting on McCarran’s work ferreting out subversives, The Nation’s Willard Shelton commented in 1951, “Inquisitors have come and gone, but the witch hunt continues, snaring more victims, manufacturing new heresies, mounting steadily in virulence.” The Supreme Court later struck down most of the law as a violation of the First Amendment.

In 1952, in an effort to bar entry to communist sympathizers and deport those already here, McCarran helped draft the immigration law that Trump is now invoking. In The Nation, civil rights lawyer Alex Brooks tried to warn readers about the bill as it made its way through Congress: “Exclusion or deportation is not based on whether an alien has actually done something wrong but on whether an immigration official is ‘satisfied’ or ‘has reason to believe’ he has. The Attorney General is even empowered to sanction deportation or deprive a resident of his precious citizenship when certain facts appear in his ‘opinion’ to warrant such drastic action.”

In 1984, the Reagan administration began an effort to deport the feminist author (and onetime Nation contributor) Margaret Randall because her writings went “against the good order and happiness of the United States.” Randall had been born in the US, but she inadvertently lost her citizenship when she became a Mexican citizen in 1967. David Cole, then one of Randall’s attorneys and now The Nation’s legal affairs correspondent, explained the stakes of her case. To enforce the 1952 law against those who posed no real threat to this country, he wrote, would be “to adopt the very totalitarian precepts from which the McCarran-Walter Act was purportedly designed to save us.”

Support independent journalism that does not fall in line

Even before February 28, the reasons for Donald Trump’s imploding approval rating were abundantly clear: untrammeled corruption and personal enrichment to the tune of billions of dollars during an affordability crisis, a foreign policy guided only by his own derelict sense of morality, and the deployment of a murderous campaign of occupation, detention, and deportation on American streets. 

Now an undeclared, unauthorized, unpopular, and unconstitutional war of aggression against Iran has spread like wildfire through the region and into Europe. A new “forever war”—with an ever-increasing likelihood of American troops on the ground—may very well be upon us.  

As we’ve seen over and over, this administration uses lies, misdirection, and attempts to flood the zone to justify its abuses of power at home and abroad. Just as Trump, Marco Rubio, and Pete Hegseth offer erratic and contradictory rationales for the attacks on Iran, the administration is also spreading the lie that the upcoming midterm elections are under threat from noncitizens on voter rolls. When these lies go unchecked, they become the basis for further authoritarian encroachment and war. 

In these dark times, independent journalism is uniquely able to uncover the falsehoods that threaten our republic—and civilians around the world—and shine a bright light on the truth. 

The Nation’s experienced team of writers, editors, and fact-checkers understands the scale of what we’re up against and the urgency with which we have to act. That’s why we’re publishing critical reporting and analysis of the war on Iran, ICE violence at home, new forms of voter suppression emerging in the courts, and much more. 

But this journalism is possible only with your support.

This March, The Nation needs to raise $50,000 to ensure that we have the resources for reporting and analysis that sets the record straight and empowers people of conscience to organize. Will you donate today?
