Chief Justice John Roberts told an audience at Rice University's Baker Institute for Public Policy in Houston on Tuesday that criticism aimed personally at Supreme Court justices crosses a line that threatens the judiciary itself.
"Personally directed hostility is dangerous, and it's got to stop," Roberts said.
The remarks arrived days after President Trump singled out Justices Amy Coney Barrett and Neil Gorsuch, both his own appointees, on Truth Social. As reported by the Daily Mail, Trump accused them of issuing "bad and wrongful rulings" and called the Supreme Court a "weaponized and unjust political organization" that "routinely sides with the radical left Democrats."
The flashpoint was a 6-3 ruling on February 20 that struck down Trump's tariffs, with the Court determining that the International Emergency Economic Powers Act did not grant the president authority to impose sweeping emergency tariffs. Roberts joined Barrett and Gorsuch in the majority. Justices Kavanaugh, Thomas, and Alito dissented.
The ruling blew a $1.6 trillion hole in government revenue projections and sent companies scrambling to file for refunds after the previous tariff authority was voided. The Trump administration immediately pivoted to a new 10 percent baseline tariff under a separate authority. That tariff, announced on February 24, applies to nearly all imports, with the administration signaling it could rise to 15 percent later this year.
That is not the response of an administration caught flat-footed. It is the response of an administration that had a contingency plan ready.
But the legal defeat clearly stung, and Trump vowed to continue calling out what he described as "bad behavior" from justices he placed on the bench. The frustration is understandable. Barrett and Gorsuch owe their seats to Trump's political capital, and the tariff agenda sits at the center of his economic vision. When your own appointees hand you a landmark loss, the impulse to say so publicly is human.
Roberts, for his part, acknowledged that scrutiny of judicial opinions is expected and "important." Decisions should be "subjected to scrutiny," he said. His objection was narrower: the shift from "legal analysis to personalities," which he called "frankly, quite dangerous."
US District Judge Lee Rosenthal, a George H.W. Bush appointee, thanked Roberts on behalf of trial judges:
"We always know that you have our backs, and that means a great deal."
That line reveals something about the current climate on the federal bench. When trial judges feel the need to publicly thank the Chief Justice for standing up for them, the temperature has clearly risen.
The statistics back that up. According to the US Marshals Service, roughly 400 federal judges have been targeted with serious threats, a 78 percent spike compared to four years ago. Judge John Coughenour, a Ronald Reagan appointee, said earlier this month that he has "never encountered the hostility" toward the judiciary he has witnessed over the past year. Coughenour told 60 Minutes he received hundreds of death threats and was subjected to swatting calls after Trump took issue with his ruling against the president's birthright citizenship executive order, which Coughenour called "blatantly unconstitutional."
Death threats and swatting calls against judges are criminal, full stop. No political disagreement justifies them. Conservatives who rightly condemned the left's campaign of intimidation against Justice Kavanaugh during his confirmation, and the attempted assassination plot against him in 2022, cannot look the other way when the target wears a different judicial robe.
There is a real and legitimate tension here, and conservatives should be honest about it rather than pretending it doesn't exist.
On one hand, the federal judiciary has spent decades accumulating power that the Founders never intended it to wield. Nationwide injunctions issued by single district judges. Policy preferences dressed up as constitutional mandates. The administrative state's favorite backstop whenever a president tries to govern. Conservatives have been on the receiving end of judicial overreach for a generation, and the frustration with an unaccountable judiciary is not manufactured. It is earned.
On the other hand, the principle of judicial independence is not a liberal idea. It is a structural feature of the constitutional order that conservatives claim to revere. The same independence that allowed this Court to overturn Roe v. Wade is the independence Roberts is asking people to respect now. You cannot celebrate the institution when it delivers your victories and then treat it as a political enemy when it doesn't.
White House spokeswoman Abigail Jackson framed the issue as one of candor:
"The American people have always valued President Trump's ability to freely speak his mind and share his thoughts directly with them. It's one of the many reasons he was resoundingly re-elected. The President will continue speaking with the same candor that the American people love to hear from him."
That candor is part of what got Trump elected, twice. Voters are tired of politicians who speak in euphemisms and govern through consultants. But there is a difference between calling a ruling wrong and calling the Court a "weaponized and unjust political organization." One is political speech. The other erodes the legitimacy of the very institution that gave conservatives their greatest legal victories of the last half-century.
The tariff fight is far from over. The administration has already rerouted its trade agenda through alternative legal authority, and the 10 percent baseline tariff is now in effect. The policy question will continue to play out in both the courts and the markets.
The institutional question is harder. Roberts is not wrong that personal attacks on judges create a permission structure for the kinds of threats the Marshals Service is now tracking at record levels. He is also not naive enough to think that a polite request from a podium in Houston will change the temperature.
What might change the temperature is conservative leaders making the case that judicial independence is a conservative value, not a concession to the left. The Court that struck down these tariffs is the same Court that ended the EPA's regulatory overreach, reined in agency power, and restored the Second Amendment. That Court exists because conservatives fought for decades to build it.
Dismantling its legitimacy is not a conservative project. It is the left's.
