Democrats spent two years insisting Donald Trump was going to defy the Supreme Court and bring the republic to its knees.
Now one of their own just did it – and Fetterman went on Fox News to say what every Senate Democrat refuses to admit.
And John Fetterman warned that a constitutional crisis will unfold after Democrats picked this fight with Trump.
Fetterman Calls Out Mamdani for Defying the Supreme Court on TPS
John Fetterman appeared on Fox News with host Kayleigh McEnany and called out Democrats for their hypocrisy.
He told McEnany that Democrats spent 2025 warning Trump was on the verge of defying court orders — and that a real constitutional crisis happens the moment a president does it.
Trump never did.
"As far as I know, the Trump administration has not defied any of those court rulings," Fetterman told McEnany.
Then he turned the spotlight on New York City Mayor Zohran Mamdani – the Democrat Socialist who just promised to defy a 6-3 Supreme Court ruling on Temporary Protected Status for Haitian and Syrian illegal aliens.
"I haven't seen the freak-out now that the Mayor of New York is saying I'm going to defy the Supreme Court ruling," Fetterman said.
His own party said nothing.
"Many of the members in my party are not calling him out," Fetterman continued, "or defend him, or just say, we really actually have to follow the court rulings – unless that's a constitutional crisis."
It is.
The Supreme Court TPS Ruling Was Clear and Mamdani Refuses to Accept It
The Supreme Court ruled 6-3 that the federal government has the authority to end Temporary Protected Status for Haitian and Syrian migrants.
Justice Samuel Alito authored the majority opinion, which held that the TPS statute itself bars judicial review of non-constitutional termination claims.
Congress wrote the law, the executive branch enforces it, and courts stay out.
That clears the way for the Trump administration to end protections for roughly 350,000 Haitians and 6,000 Syrians currently in the country.
Mamdani responded within hours by standing in front of cameras and declaring the ruling "something that we will not ever accept."
He rallied alongside New York Governor Kathy Hochul and state Attorney General Letitia James, issued a formal written declaration from City Hall, and activated a free legal hotline for affected illegal aliens.
Mamdani has no legal mechanism to restore federal immigration protections the Supreme Court just ruled the executive branch can lawfully revoke.
New York City's existing sanctuary rules prohibit local police from assisting federal immigration enforcement – and that is the full extent of what Mamdani can actually do.
His defiance is theater – a promise he cannot keep and knows it.
Democrats Who Screamed Constitutional Crisis Under Trump Are Silent on Mamdani
Democrat Senator Chris Murphy told reporters in 2025, "This isn't hyperbole to say that we are staring the death of democracy in the eyes right now."
Murphy's position was simple: elected leaders must honor court rulings.
Now a Democrat Socialist mayor is openly announcing he will not honor a court ruling – and Murphy is silent.
The pattern has a name in American history: nullification.
In 1957, Arkansas Governor Orval Faubus ordered the National Guard to block black students from entering Little Rock Central High School – defying a federal court order stemming from Brown v. Board of Education.
President Eisenhower sent in the 101st Airborne Division.
Faubus lost.
The Supremacy Clause of the Constitution does not come with a carve-out for mayors who disagree with the ruling.
Federal immigration law is not optional for New York City, regardless of how many rallies Mamdani holds.
Fetterman knows it.
"When you have the leader of the country's largest city saying we're not going to follow or honor what the Supreme Court says," Fetterman told McEnany, "that's a constitutional crisis."
His party handed him the standard two years ago.
He's holding them to it.
