The US Senate has confirmed Markwayne Mullin as secretary of the Department of Homeland Security (DHS), placing him in charge of the agency during a prolonged funding crisis and mounting operational challenges.

Mullin, a Republican from Oklahoma, was approved in a 54–45 vote on Monday. Two Democrats, John Fetterman and Martin Heinrich, joined Republicans in supporting his nomination.
Leadership Change During Crisis
Mullin replaces Kristi Noem, who was dismissed weeks earlier following a controversial immigration enforcement operation in Minneapolis in which two American citizens were killed.
His appointment comes as DHS enters its sixth week of a partial shutdown, with no clear resolution in sight. Thousands of employees, including airport security staff, remain unpaid, contributing to widespread disruption.
Absenteeism has risen sharply among Transportation Security Administration (TSA) workers, leading to long queues at airports across the country. More than 400 officers have resigned since the shutdown began.
Political Divisions Persist
Despite Mullin’s confirmation, the political deadlock over DHS funding appears unresolved. Democrats have insisted they will not support reopening the department without new restrictions on immigration enforcement agencies, including Immigration and Customs Enforcement (ICE) and Customs and Border Protection.
These proposed measures include requiring agents to display identification, limiting the use of face coverings and mandating judicial warrants for certain operations.
Republicans have rejected these conditions, and Donald Trump has urged his party to resist compromise, prolonging the standoff.
Scrutiny Over Nomination
Mullin’s nomination faced criticism during the confirmation process. Rand Paul opposed his appointment, questioning his temperament following a tense committee hearing.
Democratic lawmakers also raised concerns about his experience and transparency, particularly regarding a previously undisclosed overseas trip he described as classified.
Gary Peters, a senior Democrat on the Homeland Security Committee, said Mullin had not demonstrated the necessary qualifications to lead the department.
Others emphasised that their opposition was rooted in broader policy disagreements rather than personal objections.
Background and Challenges Ahead
Mullin, 48, previously worked in his family’s plumbing business and had a career as a professional mixed martial arts fighter before entering politics. He was first elected to Congress in 2012 and later won a Senate seat in a special election.
He is a member of the Cherokee Nation and a long-time political ally of Trump.
His new role will test his influence in Washington as lawmakers attempt to resolve the funding impasse and address operational pressures within DHS.
With airport disruptions continuing and tensions over immigration policy unresolved, Mullin takes office at a time of significant uncertainty for one of the US government’s largest and most complex departments.
