Department of Homeland Security Secretary Markwayne Mullin forcefully pushed back against Sen. Chris Murphy (D-CT) during a tense Senate hearing on Tuesday.
Mullin accused the Democrat of spreading false claims about DHS and endangering federal law enforcement officers through inflammatory rhetoric.

The clash occurred during a hearing on the Department of Homeland Security’s fiscal year 2027 budget request.
Lawmakers debated funding priorities for border security, immigration enforcement, and other homeland security programs.
Murphy opened his remarks with a sharp attack on the Trump administration’s handling of immigration enforcement and compliance with court orders.
The Connecticut Democrat claimed that DHS had repeatedly ignored judicial rulings and suggested the department was operating outside the bounds of the law.
“On 96 occasions, DHS was caught violating the law, was ordered to obey the law, and 96 times ignored the judge in one state,” Murphy said during the hearing.

“That is stunning, and it should be unacceptable to anyone on this committee who claims to care about the rule of law,” Murphy added.
Murphy also pressed Mullin on whether he would continue to follow court orders and judicial directives governing the department’s activities.
The DHS secretary immediately challenged the premise of Murphy’s criticism, arguing that the senator was misrepresenting both the department’s actions and the work performed by hundreds of thousands of federal employees.
“The outlandish claims you made there is just flat wrong,” Mullin responded.
The secretary argued that DHS is carrying out laws that Congress itself enacted and rejected Murphy’s characterization of the department as operating unlawfully.
“You start saying we’re breaking the law, and you really start looking at it, and we’re enforcing laws that Congress did pass,” Mullin said. “That’s reckless.”
The exchange quickly escalated as Mullin broadened his defense beyond administration policies and focused on the impact he believes such criticism has on frontline law enforcement personnel.
“For you to throw my 275,000 employees underneath DHS, with a broad stroke like that, is reckless and irresponsible on your part,” Mullin said.
The secretary emphasized that DHS personnel, including Border Patrol agents, ICE officers, Transportation Security Administration employees, Secret Service agents, and other federal law enforcement officials, are carrying out duties specifically authorized by Congress.
“We’re doing the job that Congress gave us the authority to do,” Mullin continued. “Our men and women out there every single day are enforcing laws. If you don’t like the laws, you can change them.”
One of the most striking moments of the hearing came when Mullin connected political rhetoric surrounding immigration enforcement to rising threats against federal agents.
The secretary argued that language describing DHS personnel as “dangerous,” “lawless,” or “unconstitutional” contributes to a hostile environment that places officers at greater risk.
“When you throw out reckless terms, and you start referring to our agents as being ‘dangerous, unconstitutional, and lawless,’ that’s why our agents’ death threats are up by 8,000%,” Mullin said.

He also pointed to what he described as a sharp increase in assaults against federal officers carrying out immigration enforcement and border security missions.
“That’s why assaults on our officers are up by 1,300%,” Mullin said. “Senator Murphy, is that what you want?”
The heated exchange comes amid an increasingly contentious national debate over immigration enforcement as the Trump administration continues to pursue an aggressive border security agenda.
Democrats have criticized many of the administration’s policies as overly aggressive and have accused DHS of exceeding legal boundaries in some enforcement operations.
Republicans have countered that many of those criticisms unfairly target rank-and-file federal officers who are simply carrying out laws enacted by Congress.
The secretary’s defense of DHS employees drew praise from many Republicans, who have argued that federal agents face growing threats while performing increasingly difficult assignments related to border security and immigration enforcement.
