President Donald Trump is growing impatient with Department of Homeland Security Secretary Markwayne Mullin, whom he views as "weak and off-message," according to reporting by The Wall Street Journal.

White House insiders told the Journal that Trump is "increasingly frustrated" with Mullin over a series of remarks that have angered the president's outside allies. Trump appointed Mullin, a former Oklahoma senator, to replace Kristi Noem after dismissing her in March. At the time, Trump told advisors he was weary of the infighting at DHS under Noem's leadership. The back-to-back personnel changes underscore a pattern of turbulence at DHS, an agency that has seen multiple leadership transitions in recent years. Despite his current frustrations, insiders say the president has no plans to fire Mullin, who is only four months into the role.

A senior Trump administration official confirmed to the Journal that the president is frustrated but does not intend to dismiss Mullin, noting that Trump is "souring on him."

Tensions peaked in August when Mullin addressed the National Governors Association and said the claim that immigrants take American jobs is "true in some industries, it's not true for all industries." He also suggested that immigration could help offset a shrinking labor force. The remarks placed Mullin at odds with the hardline immigration posture that has been a defining theme of Trump's political brand, touching on a long-running policy debate between business groups citing labor shortages and enforcement-first advocates. Right-wing influencer Laura Loomer, who regularly has the president's ear, responded on social media by stating that Mullin has "done absolutely nothing to increase the rate of mass deportations," the Journal reported.

Mullin also found himself out of step with the president following two fatal shootings by Immigration and Customs Enforcement (ICE) agents in Maine and Texas. A senior administration official told the Journal that Trump was "annoyed" and had not been informed in advance of a policy change that halted most vehicle stops by federal immigration officials.

Additionally, insiders told the Journal that Trump was angered by Mullin's suggestion to cancel the Fourth of July fireworks display on the National Mall due to severe weather concerns.

A DHS spokeswoman told the Journal that the administration is "one team, and we have one fight." A White House spokeswoman added that Trump "has confidence in his cabinet to carry out the agenda the American people voted for."
