In a significant cabinet reshuffle, former President Donald Trump has announced the replacement of Homeland Security Secretary Kristi Noem with Oklahoma Senator Markwayne Mullin. The decision was communicated through Trump’s Truth Social platform on Thursday, March 5, 2026, citing bipartisan dissatisfaction with Noem’s leadership during her tenure.

The move comes amid ongoing challenges at the Department of Homeland Security, including border security management, immigration policy implementation, and counterterrorism efforts. Noem, who previously served as Governor of South Dakota before assuming the cabinet position, faced increasing criticism from both Republican and Democratic lawmakers regarding her administration’s handling of these complex issues.

Senator Mullin, a Republican from Oklahoma and former professional mixed martial artist turned politician, brings a different perspective to the role. Having served on several committees relevant to homeland security matters, Mullin has established himself as a staunch conservative voice on border protection and national security issues. His appointment signals a potential shift in policy direction and operational approach within the department.

The transition occurs during a period of heightened global tensions and domestic security concerns, making the leadership change particularly significant. The Department of Homeland Security remains one of the most critical federal agencies, with responsibilities spanning from cybersecurity to emergency response coordination.

This cabinet-level change reflects the ongoing evolution of Trump’s administrative team as he continues to shape his policy priorities. The swift nature of the announcement, bypassing traditional press briefing channels, demonstrates Trump’s continued preference for direct communication through social media platforms.

In a significant cabinet reshuffle, President Donald Trump has terminated Kristi Noem as Secretary of Homeland Security, replacing her with Oklahoma Senator Markwayne Mullin. The announcement came via Trump’s Truth Social platform on Thursday, marking the first major personnel change in Trump’s second-term administration.

Noem’s dismissal follows months of mounting controversies surrounding her unconventional leadership style. Despite initially emerging as one of the administration’s brightest stars for her hands-on approach to immigration enforcement—including participating in raids while wearing tactical gear—Noem increasingly faced criticism from both political parties.

Her tenure became particularly contentious after she authorized a $220 million advertising campaign featuring herself and spent nearly $200 million on luxury jets for official travel. The situation escalated when Trump publicly contradicted her congressional testimony about his awareness of these expenditures, stating he ‘never knew anything about it.’

The final straw appears to have been the administration’s controversial immigration crackdown in Minneapolis last January, where federal agents shot and killed two U.S. citizens. Trump subsequently dispatched border czar Tom Homan to manage the response, effectively sidelining Noem and signaling declining confidence in her leadership.

Noem will transition to a new role as special envoy for the Shield of the Americas initiative, a Western hemisphere security program. Her replacement, Senator Mullin, represents another conservative Trump ally with hardline immigration views, suggesting policy continuity despite the personnel change.

This move demonstrates Trump’s continued willingness to reshuffle his team when political winds shift, particularly as Republicans face electoral challenges regarding public perception of aggressive immigration tactics.

In a decisive partisan vote, the US House of Representatives has blocked a congressional resolution seeking to limit President Donald Trump’s military authority regarding Iran. The 219-212 rejection followed party lines and came just one day after a similar legislative effort failed in the Senate.

The War Powers Resolution, while largely symbolic given an anticipated presidential veto, represented growing congressional concern over executive military actions. Democratic lawmakers have intensified their criticism of the administration’s unilateral strike authorization, questioning whether the alleged Iranian threat met the legal standard of “imminent” danger required for independent presidential action.

House Speaker Mike Johnson defended the rejection, stating, “The prospect of stripping our commander in chief’s authority to complete this mission represents a frightening scenario.” The administration has since revised its conflict timeline projection to eight weeks—nearly double President Trump’s initial weekend estimate.

Constitutional debates surrounding the 1973 War Powers Act resurfaced during deliberations. Secretary of State Marco Rubio noted that “no presidential administration has ever accepted the War Powers Act as constitutional—whether Republican or Democratic.” The administration maintains it complied with legal requirements by notifying the bipartisan “Gang of Eight” congressional leaders before initiating strikes.

Some Republican legislators indicated their opposition might shift if the conflict escalates, suggesting conditional support for future war powers limitations. The resolution would have terminated unauthorized military engagement in Iran without congressional approval.

This development occurs against the backdrop of previous unilateral military actions ordered by President Trump, including strikes against Iranian nuclear facilities and the January operation targeting Venezuelan President Nicolás Maduro.

In a significant cabinet reshuffle, President Donald Trump has nominated Oklahoma Senator Markwayne Mullin to lead the Department of Homeland Security (DHS), succeeding the departed Kristi Noem. The announcement positions the first-term senator, a former mixed martial arts fighter and staunch Trump ally, for one of the administration’s most critical security roles.

Senator Mullin’s nomination requires confirmation by the Senate. He is poised to become the second individual to helm the DHS during President Trump’s second term, stepping into an agency currently grappling with a partial government shutdown and intense scrutiny over its immigration enforcement tactics.

A vocal supporter of the administration’s stringent immigration policies, Mullin has consistently praised the DHS’s efforts to detain undocumented immigrants. However, he has also broken ranks on certain issues, publicly criticizing the ongoing government shutdown that has frozen funding for the department. In a recent CNN interview, he lambasted the political maneuvering, stating, ‘They’re not stopping ICE from doing their job,’ despite the funding lapse.

The nominee will assume leadership of an agency facing heightened criticism, particularly following recent incidents where federal immigration officials were involved in the deaths of two U.S. citizens in Minnesota. Mullin’s previous public statements reveal unwavering support for federal agents. Following the shooting of Alex Pretti in Minneapolis, he declared on social media that obstructing law enforcement is a felony and commended ICE agents as ‘patriots doing a difficult job under an 8,000% rise in death threats.’

Before his political career, Mullin, a father of six, built a family plumbing business with his wife over two decades. He was sworn into the U.S. Senate in 2023, bringing his business background and combative, supportive stance on Trump’s agenda to Washington.

A coalition comprising 24 U.S. states has initiated a significant legal challenge against the Trump administration’s latest tariff measures, marking an escalation in the ongoing constitutional struggle over presidential trade authority. The lawsuit, spearheaded by Democratic attorneys general from New York, California, Oregon, and Arizona, was filed Thursday in the U.S. Court of International Trade.

The legal action emerges just weeks after the Supreme Court invalidated previous tariffs imposed by the administration under the International Emergency Economic Powers Act. In response to that ruling, the White House swiftly implemented a new 10% global tariff utilizing Section 122 of the Trade Act of 1974—a statute the administration claims provides legitimate authority for such measures.

The plaintiffs argue that both the constitutional separation of powers and statutory interpretation principles are being violated. ‘The president’s rationale for these unlawful tariffs has gone from unreasonable to ridiculous,’ stated California Attorney General Rob Bonta during Thursday’s press conference. Arizona Attorney General Kris Mayes characterized the administration’s move as ‘the same illegal power-grab under a different statute.’

White House spokesperson Kush Desai defended the tariffs as a legitimate exercise of congressionally granted authority, stating the administration would ‘vigorously’ defend the measures in court. The administration maintains that Section 122 empowers the president to address balance-of-payments deficits without congressional approval for up to 150 days, with tariff rates potentially reaching 15%.

The legal challenge seeks both injunctive relief to prevent implementation of the new tariffs and refunds for any duties already collected under Section 122. This development occurs alongside a separate federal court order requiring Customs and Border Protection to issue refunds for previously struck-down tariffs, suggesting a developing judicial consensus regarding the limits of presidential trade authority.

South Dakota Governor Kristi Noem finds herself at the center of a political firestorm, drawing sharp criticism from both sides of the political aisle. The controversy emerged following recent congressional hearings that scrutinized her performance and decision-making. These developments occurred immediately preceding her departure from the position of Department of Homeland Security Secretary, though official sources clarify she was not formally serving in this capacity at the time of the hearings.

The bipartisan criticism represents a rare moment of political alignment in Washington, with Democratic and Republican leaders expressing concerns about gubernatorial conduct and potential ethical considerations. The hearings examined various aspects of Noem’s administrative approach and policy implementations during her tenure in public service.

Political analysts note that the timing of these hearings, coinciding with her transition from federal security responsibilities, has amplified the scrutiny on her political future. The situation highlights the increasing pressure on public officials to maintain bipartisan support while navigating complex governmental roles. This case demonstrates how quickly political fortunes can change in Washington’s highly charged environment, where bipartisan criticism often signals significant challenges for a political career.
