Homeland Security Secretary Markwayne Mullin dismissed a Republican congresswoman's campaign ad attacking Trump's immigration enforcement as political posturing, and rejected her claim that half of ICE detainees had no criminal record.
Mullin appeared on CNN's "Inside Politics" on Friday to respond directly to Rep. María Elvira Salazar, R-Fla., who released an ad the day before warning President Trump that "some of your immigration enforcement efforts have gone too far." The DHS secretary spoke bluntly: every person detained after entering the country illegally is, by definition, a criminal, he said, because federal law makes improper entry a criminal offense in specified circumstances.
The exchange marks a rare public split between a Republican lawmaker and the Trump administration on its signature issue, and an even rarer instance of a Cabinet secretary going on national television to rebuke a member of his own party by name.
Salazar's ad, released Thursday, was unusually direct for a Republican member of Congress. She addressed Trump personally, telling him to "be careful what your advisers are telling you about immigration policy." She cited a specific figure: "In July, 50% of the 50,000 people that were detained had no criminal record."
Salazar represents Florida's 27th Congressional District, which covers much of Miami-Dade County. Newsmax reported that roughly 74% of the district's population is Hispanic, according to The Washington Post, a demographic reality that shapes Salazar's political calculus as she faces Democrat Eliott Rodriguez, a former television news anchor, in November.
The congresswoman framed her criticism around loyalty, not opposition. She said Hispanic voters who helped Trump return to the White House in 2024 "feel betrayed today." And she drew a line that stopped short of calling for amnesty:
"I'm not talking about giving them amnesty. I'm talking about giving them a dignified life in this promised land."
CBS News has reported that Salazar has previously criticized aspects of the administration's immigration policies while also supporting increased enforcement. She has advocated immigration reforms that would provide legal status for some illegal immigrants who meet specified requirements, a position that puts her at odds with the enforcement-first wing of the party.
Mullin's administration has been dealing with broader questions about immigration enforcement and fraud. The DHS secretary has also been involved in a federal investigation into Rep. Ilhan Omar over immigration-related allegations, demonstrating the department's willingness to pursue enforcement across party lines.
On CNN, anchor Dana Bash pressed Mullin on Salazar's claim that half of ICE detainees lacked criminal records. Mullin's response was blunt:
"I will say that's actually not true. Every one of them was a criminal because they broke our nation's laws when they came across our borders illegally."
He went further, stating that anyone who crossed the border illegally "chose to become a criminal at that point, regardless." It was a rhetorical broadside aimed at the distinction Salazar tried to draw between violent offenders and people whose only violation was entering the country without authorization.
Federal law does make improper entry into the United States a criminal offense in specified circumstances, including certain first-time crossings. But the legal picture has wrinkles. Other immigration violations, including unlawful presence, staying past a visa's expiration, for example, can be civil rather than criminal violations. Mullin's framing collapses that distinction. Whether that matters politically is another question. For most conservative voters, the point is straightforward: you broke the law to get here, and the government has every right to remove you.
Congressional oversight of immigration fraud has intensified in recent months. Lawmakers like Rep. James Comer have called on the Trump administration to release evidence in ongoing immigration-related probes, reflecting a broader push within the GOP to hold violators accountable regardless of political status.
Bash also asked Mullin whether the administration was pursuing people without criminal records to meet a daily arrest quota imposed by the White House. Mullin denied it flatly:
"I have never talked to anybody at the White House about any quota."
The quota question has circulated in media coverage of ICE operations, but Mullin offered no ambiguity. He framed the department's work as a legal obligation, not a numbers game:
"We don't pick and choose which laws we enforce. We enforce the immigration policy that Congress passed and obligated Department of Homeland Security to enforce."
That framing puts the burden back on Congress. If lawmakers like Salazar object to who is being detained, Mullin's argument goes, they should change the law, not blame the agency tasked with enforcing it.
The scale of current enforcement operations adds context to the dispute. Breitbart reported earlier this year that ICE is arresting over 1,900 individuals per day and detaining more than 60,000 migrants going through the deportation process. Deportations are running at roughly 1,200 people per day, approximately 440,000 per year, according to analyst Austin Kocher. Border czar Tom Homan has promised the pace will only increase, saying the administration is pursuing "smarter enforcement," not lesser enforcement.
Mullin seemed to understand exactly what Salazar's ad was, and said so. He dismissed it as campaign positioning without pretending to be offended by it:
"A political campaign ad is a political campaign ad. I completely understand it. But that's not going to keep us, the men and women at the Department of Homeland Security, from doing our job."
That response was measured, and it boxed Salazar in. She can run her ads and make her appeals to Miami-Dade's Hispanic voters. But the policy is not changing because a Republican in a swing district needs a campaign clip.
Salazar's district presents a genuine political challenge. A heavily Hispanic constituency that helped deliver Florida for Trump in 2024 may not be uniformly enthusiastic about enforcement operations that sweep up people without violent criminal histories. Salazar is trying to thread a needle: support the president broadly while carving out space on the one issue where her voters might feel the enforcement most directly.
The legal complexities of immigration enforcement have surfaced in other high-profile cases as well. Federal investigators have encountered significant procedural obstacles in cases involving allegations of immigration fraud, where the distinction between criminal and civil violations can determine whether the government has the authority to act.
But the needle-threading has a cost. Salazar did not cite a source for her claim that 50% of 50,000 July detainees had no criminal record. She did not name the dataset, the agency report, or the government filing behind the number. Mullin disputed the claim directly, and without a verifiable source, the statistic hangs in the air, a campaign talking point dressed up as policy analysis.
Meanwhile, the administration's enforcement apparatus has expanded its focus. Border czar Tom Homan has signaled that operations will move beyond criminal aliens into what some analysts describe as a broader phase of deportations targeting non-violent migrants, precisely the population Salazar's ad was designed to defend. The administration has also pursued criminal investigations into immigration fraud at the highest levels of government, signaling that enforcement is not limited to the border.
Several gaps remain in the congresswoman's public case. She warned Trump about unnamed "advisers" but did not identify who she believes is giving the president bad counsel on immigration. She cited a specific detention figure but offered no sourcing. And she positioned herself as a defender of Hispanic voters' interests without explaining which enforcement actions, specifically, she considers excessive, or what standard she would apply.
Mullin, for his part, left no daylight between himself and the White House. He denied quotas, defended every arrest as lawful, and made clear that campaign ads from fellow Republicans would not alter DHS operations.
Salazar is free to run whatever ads her reelection campaign requires. But when a Republican member of Congress attacks her own party's enforcement of existing law, without sourcing her claims or naming an alternative, it looks less like principled dissent and more like a politician who wants credit for toughness without any of the consequences.
